- Removed deprecated functions related to document parsing and blob storage in blobstore.ts.
- Introduced new PDF rendering logic in pdf-preview-renderer.ts and pdf-preview-pdfjs-runtime.ts.
- Updated previews-render.ts to utilize the new PDF rendering functions.
- Refactored user-whisper-align-job.ts to use the compute-worker client for alignment requests.
- Enhanced artifact.ts and operation.ts to validate parsed PDF artifacts and resolve current PDF parses.
- Updated snapshot.ts to align with new worker operation types.
- Adjusted runtime-config.ts to check for compute-worker availability.
- Modified types in parsed-pdf.ts and tts.ts to reflect changes in the compute-worker protocol.
- Added unit tests for PDF artifact validation and compute-worker client contract.
- Removed obsolete pdf-op-key.vitest.spec.ts test file.
Introduce automatic healing for stale PDF parse states in API routes. Add
`isDocumentParseStateStale` utility and use a shared `COMPUTE_OP_STALE_MS`
environment variable (with config getter) to control the stale window for both
worker op replacement and app-side parse-state healing. Update documentation and
environment variable references to reflect new config.
Enables automatic marking of stuck parses as failed, improving reliability and
retry behavior in distributed compute environments.
