docs: split v4/v5 content trees and fix version switcher end-to-end

[karthikscale3]

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs

Column Definitions

• Workflow Time: Runtime reported by workflow (completedAt - createdAt) - primary metric
• TTFB: Time to First Byte - time from workflow start until first stream byte received (stream benchmarks only)

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs

Summary

Content restructuring

• Split docs/content/docs/ into docs/content/docs/v4/ and docs/content/docs/v5/ — each version is now a fully independent content tree with no shared-file coupling or preRelease frontmatter filtering
• v4 excludes the four v5-only pages (AbortController cancellation docs, abort-signal-timeout error, and serializable-abort-controller internal page)
• v5 retains all pages; preRelease frontmatter field removed (no longer meaningful with separate folders)
• Removed AbortController / AbortSignal from the v4 serialization page (moved to v5 only)

Fumadocs source split

• Added v4docs and v5docs as separate defineDocs() collections in source.config.ts pointing to content/docs/v4 and content/docs/v5
• source.ts now exports both source (v4) and v5Source (v5), both with baseUrl: /docs

Version routing fixes

• version-source.ts simplified: removed filterPreReleaseFromNodes / isPreReleaseUrl logic; v4 sidebar uses source, v5 uses v5Source + existing rewriteNodeUrls
• v4 page.tsx: removed the preRelease guard (v4Source simply doesn't contain those pages)
• v5 page.tsx: uses v5Source for getPage, generateStaticParams, and generateMetadata; v5Link wrapper rewrites /docs/… hrefs to /v5/docs/… so inline MDX links stay in the v5 context
• buildVersionUrl now handles /cookbook/… paths with the same version-prefix logic as /docs/…; non-versioned routes (worlds, api) return unchanged

Versioned cookbook

• Added app/[lang]/v5/cookbook/ layout + page (mirrors v4, uses v5Source and rewriteCookbookUrlForVersion)
• getCookbookTree accepts a versionPrefix parameter; sidebar URLs are prefixed accordingly (/v5/cookbook/…)
• cookbook-tree.ts: added skipVersions?: string[] per-recipe field for version-specific exclusions; distributed-abort-controller marked skipVersions: ['v5'] so it shows in v4 but not v5

Version switcher — state & navigation

• New VersionProvider context (hooks/geistdocs/use-version.tsx) backed by localStorage: URL is the source of truth on versioned pages; localStorage carries the preference across non-versioned pages (worlds, etc.)
• VersionSwitcher uses useVersion() context; now visible on all pages including cookbook (no longer hidden on non-docs routes)
• DesktopMenu and MobileMenu read activeVersion from context so "Docs" and "Cookbook" navbar links resolve to the correct version prefix on every page
• switchVersion does a HEAD probe before navigating; falls back to the versioned cookbook or docs home if the target page doesn't exist in that version — handles both v4-only → v5 (distributed-abort-controller) and v5-only → v4 (cancellation docs) cases

Cookbook content (v5)

• Rewrote agent-cancellation recipe using a single AbortController + hook pattern; removed the Hard Cancellation vs Stop Signal two-approach comparison and comparison table
• Deleted distributed-abort-controller recipe from v5 (native AbortController serialization in v5 makes it unnecessary)
• Removed all references to distributed-abort-controller from cookbook/index.mdx, common-patterns/timeouts.mdx, advanced/meta.json, and the agent-cancellation page

Test plan

• /docs/… (v4) pages load correctly; v5-only pages (/docs/foundations/cancellation, etc.) return 404
• /v5/docs/… pages load correctly including the four v5-only pages
• Version switcher shows correct version on docs, cookbook, and worlds pages
• Switching v4 → v5 on a docs page navigates to the same page under /v5/docs/…
• Switching v5 → v4 on a v5-only page falls back to /docs/getting-started
• Switching versions on /cookbook/… navigates to the same recipe under /v5/cookbook/… (or falls back if not present)
• Switching v4 → v5 on /cookbook/advanced/distributed-abort-controller falls back to /v5/cookbook
• Navbar "Docs" and "Cookbook" links resolve to the active version's prefix on all pages
• Version preference is preserved when navigating from docs → cookbook → back to docs
