- Rewrite LibraryCache from JSON (cache dir) to SQLite (data dir with WAL) - Each track gets a stable UUID so play stats survive file renames/re-encodes - Thread-safe via PRAGMA busy_timeout + RLock - Automatic backup rotation (.backup, .bak) on every write - One-shot migration from old ~/.cache/library_cache.json - Add SessionStore (~/.local/share/session.json) for playback state - Add SplashOverlay with spinning animation on first (empty-DB) launch - _scan_library() now accepts on_progress callback for the overlay - Fix _mtime → mtime SQLite column name lookup in recently-added filter - PlaylistManager path migrated to ~/.local/share/ with auto-migration - Metadata sync: remove dead consume_play_deltas(), use library API
