Replace the full in-memory List<LocalLibraryItem> in LocalLibraryState with a lightweight lookup index (ISRCs, matchKeys, filePathById) and database-backed FutureProvider.family pagination providers. Database changes: - Add library schema v7 with normalized lookup columns (track_name_norm, artist_name_norm, album_name_norm, album_artist_norm, match_key, album_key) and corresponding indexes - Backfill normalized columns on migration from v6 - Add getPage, getPageCount, getAlbumPage, getAlbumCount, getLookupIndex, getCoverPaths, getByFilePath, findFirstByTrackAndArtist DB methods Provider changes: - LocalLibraryState no longer holds items list; uses totalCount and loadedIndexVersion for change tracking - Deprecate synchronous getByIsrc/findByTrackAndArtist (return null); add async findExistingAsync, getByIsrcAsync, getById on notifier - Add localLibraryPageProvider, localLibraryAlbumPageProvider, localLibraryAllItemsProvider family providers for paginated access - Add localLibraryCoverProvider and localLibraryFirstCoverProvider for async cover path resolution from DB Screen migrations: - album/artist/playlist screens use findExistingAsync for playback - library_tracks_folder_screen uses async cover providers and existsInLibrary for local library indicator - queue_tab watches localLibraryAllItemsProvider instead of state.items - library_settings_page uses state.totalCount - playback_provider uses findExistingAsync Track metadata screen: - Replace pushReplacement navigation with in-place state swap using AnimatedSwitcher for smooth cross-fade transitions on track swipe - Add metadataLoadGeneration counter to prevent stale async callbacks - Reset all transient state (lyrics, cover, file check) on track change
