The @workflow/vite package version in pre.json is incorrect - it shows 4.0.0-beta.1 but should be 4.0.0-beta.2 to match the package.json version.

Analysis
Version mismatch in .changeset/pre.json for @workflow/vite
What fails: The initialVersions section in .changeset/pre.json tracks outdated package versions, causing the changeset system to lose sync with actual package versions during pre-release cycles.
How to reproduce:
# Compare versions in the two files
grep "@workflow/vite" .changeset/pre.json
grep "\"version\"" packages/vite/package.jsonResult:
.changeset/pre.jsonline 41:"@workflow/vite": "4.0.0-beta.1"packages/vite/package.jsonline 4:"version": "4.0.0-beta.2"
Expected: Both files should show the same version. The package.json is the source of truth, and the pre.json initialVersions should match the actual current package versions as documented in packages/vite/CHANGELOG.md which confirms 4.0.0-beta.2 was released in PR #501.

🔧 Build Fix:
The workflow package's TypeScript configuration generates separate source map files instead of embedding them inline. Since these .js.map files are excluded from git, they're missing during CI builds, causing Turbopack to fail when it tries to resolve source map references. Configuring the package to use inlineSourceMap instead fixes the issue by embedding source maps directly in the JavaScript output.

Analysis
Missing source map file causes Turbopack build failure
What fails: Turbopack build for nextjs-turbopack fails when attempting to process JavaScript files from the workflow package that reference missing source map files.
How to reproduce:
pnpm install
pnpm exec turbo run build --filter nextjs-turbopackResult:
ERROR failed to read input source map: failed to find input source map file "stdlib.js.map" in "packages/workflow/dist/stdlib.js" file as either "packages/workflow/dist/stdlib.js.map" or with appended .map
...
Code generation for chunk item errored
An error occurred while generating the chunk item [project]/workbench/nextjs-turbopack/app/page.tsx [app-client] (ecmascript)
Root cause: The packages/workflow/tsconfig.json was configured with sourceMap: true (inherited from base.json), which causes TypeScript to generate separate .js.map source map files. These files are:
- Not committed to git (.gitignore excludes
/packages/*/dist) - Not available during CI builds
- Cause Turbopack to fail when it encounters source map references it cannot resolve
Solution: Configure the workflow package to use inlineSourceMap: true and sourceMap: false, which embeds source maps directly in the JavaScript files as base64-encoded data URIs instead of separate files. This prevents the missing file issue since no separate files are referenced.
This matches the fix applied to @workflow/core in commit 2fde24e.
