Add Week 9 Smart Features: collections, artwork, predictive prefetch
...
Smart Collections (musicfs-search/src/collections.rs):
- CollectionStore with thread-safe Mutex<Connection>
- CollectionQuery enum: Match, DateRange, RecentlyAdded/Played, MostPlayed, Genre, Compound
- Builtin collections for Recently Added, 80s/90s Music
Artwork Extraction & Caching:
- ArtworkExtractor using symphonia Visual (musicfs-metadata)
- ArtworkCache with CAS storage + on-demand resize (musicfs-cache)
- ArtType: Front/Back/Other, ArtSize: Thumbnail/Medium/Full
Predictive Prefetching:
- PatternStore tracks access patterns with sequence prediction
- PrefetchEngine listens to FileAccessed events, prefetches predictions
- PrefetchOps exposes /.prefetch/ virtual directory with status/hints
Oracle review fixes applied:
- CollectionStore uses Mutex for thread safety
- FileAccessed event now includes file_id for canonical correlation
- JSON parse warnings in collection deserialization
130 tests pass (15 new tests added)
