Pull request overview

Updates the SvelteKit workbench app to newer SvelteKit/Svelte and adapter versions, bringing the example project in workbench/sveltekit in line with the latest compatible SvelteKit ecosystem releases.

Changes:

Bumped @sveltejs/kit and svelte versions for the SvelteKit workbench.
Bumped SvelteKit adapters (@sveltejs/adapter-node, @sveltejs/adapter-vercel) to newer releases.
Regenerated pnpm-lock.yaml to capture updated transitive dependency resolution (notably Rollup/Vercel-related deps).

With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.

+ "@sveltejs/adapter-vercel": "^6.3.3",


With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.

With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.

With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.

With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.

Bumped @sveltejs/kit and svelte versions for the SvelteKit workbench.
Bumped SvelteKit adapters (@sveltejs/adapter-node, @sveltejs/adapter-vercel) to newer releases.
Regenerated pnpm-lock.yaml to capture updated transitive dependency resolution (notably Rollup/Vercel-related deps).

With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.

With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.

With these bumped SvelteKit deps, some of the resolved packages (e.g. @sveltejs/adapter-vercel and @sveltejs/vite-plugin-svelte) now declare Node engine minimums (>=20 / ^20.19). Since this workbench has engine-strict=true in workbench/sveltekit/.npmrc, installs will hard-fail on older Node versions, but this package.json doesn’t declare an engines.node requirement. Consider adding an explicit engines field (or updating the workbench README) so the Node requirement is clear up-front.
