- Add interruptible stop events to background workers so shutdown
wakes out of long sleeps instead of waiting on fixed delays.
- Stop scan managers, repair worker, executors, and cleanup helpers
deterministically so process exit does not leave background threads
alive.
- Add startup warnings for stale SQLite WAL/SHM sidecars so unclean
shutdowns are easier to spot before init/migration errors cascade.
- Prevent forced kills from leaving SQLite sidecars behind, which
made rollbacks to older branches fail with malformed database
errors.
New repair job that scans the library for tracks filed under "Unknown
Artist" and corrects them. Resolves correct metadata by:
1. Reading embedded file tags (if file has correct artist)
2. Looking up by source track ID (Spotify/Deezer/iTunes)
3. Searching by title as last resort
Dry run mode (default) creates findings for review. Live mode re-tags
the audio file, moves it to the correct folder structure, and updates
the database. Includes fix handler for applying individual findings.
