- Move IndexingPipeline.run() into Worker Threads via WorkerPool
- Add dedicated embedding worker thread with single model instance
- Add stage/stageDetail columns to indexing_jobs schema
- Create ProgressBroadcaster for SSE channel management
- Add SSE endpoints: GET /api/v1/jobs/:id/stream, GET /api/v1/jobs/stream
- Replace UI polling with EventSource on repo detail and admin pages

- Build worker entries separately via esbuild
Implements the end-to-end indexing pipeline with a SQLite-backed job
queue, startup recovery, and REST API endpoints for job status.
- IndexingPipeline: orchestrates crawl → parse → atomic replace → embed
→ repo stats update with progress tracking at each stage
- JobQueue: sequential SQLite-backed queue (no external broker), deduplicates
active jobs per repository, drains queued jobs on startup
- startup.ts: stale job recovery (running→failed), repo state reset, singleton
initialization wired from hooks.server.ts
- GET /api/v1/jobs with repositoryId/status/limit filtering
- GET /api/v1/jobs/[id] single job lookup
- hooks.server.ts: initializes DB and pipeline on server start
- 18 unit tests covering queue, pipeline stages, recovery, and atomicity
