fix: stabilize library scan IDs, pause queue behavior, and scan race condition

Browse Source 
- Generate stable SHA-1 based IDs for SAF-scanned library items to prevent null ID crashes on the Dart side
- Suppress false queue-complete notification when user pauses instead of finishing the queue, and break out of parallel loop immediately when paused with no active downloads
- Use SQLite as the single source of truth for library scan results to fix a race condition where auto-scan could fire before provider state finished loading, dropping unchanged rows
