Version rolled back from v4.x to v3.7.0. After extensive work on v4's
internal streaming engine, smart queue, DASH pipeline, and media controls,
we realized v3 was already feature-complete. Adding more big features
only made maintenance increasingly difficult and the developer's life
miserable. Stripped back to what works: external player only, cleaner
codebase, sustainable long-term.
- Remove just_audio, audio_service, audio_session and entire internal
playback engine (smart queue, notification, shuffle/repeat, prefetch)
- Remove PlaybackItem model, MiniPlayerBar widget, notification drawables
- Remove playerMode setting (external-only now)
- Migrate MainActivity from AudioServiceFragmentActivity to
FlutterFragmentActivity
- Migrate Qobuz to MusicDL API
- Update changelog with v3.7.0 rollback explanation
- Extract normalizeOptionalString() to lib/utils/string_utils.dart from download_queue_provider and track_metadata_screen
- Extract PrioritySettingsScaffold widget from lyrics and metadata priority pages, reducing ~280 lines of duplication
- Extract _ensureDefaultDocumentsOutputDir/_ensureDefaultAndroidMusicOutputDir in download queue provider

fallback in download history lookup chain (Spotify ID → ISRC → name+artist)
- Apply same name+artist fallback to isDownloaded check in track options sheet
- Add missing library_database.dart import for LocalLibraryItem
- Add multi-select support to library_tracks_folder_screen (wishlist, loved,
playlist) with long-press to enter selection mode, animated bottom bar with
batch remove/download/add-to-playlist actions, and PopScope exit handling

playlist thumbnail widget and cover image support

isTrackInAnyPlaylist/hasPlaylistTracks accessors
- Eagerly initialize localLibraryProvider and libraryCollectionsProvider
- Enable SQLite WAL mode and PRAGMA synchronous=NORMAL across all databases
- Go backend: duplicate SAF output FDs before provider attempts to prevent
fdsan abort on fallback retries; close detached FDs after download completes

fallback to HTTP on transport-level failures, preventing redirect loops
- Go backend: enforce HTTPS-only for extension sandbox HTTP clients
- Replace SharedPreferences with SQLite (AppStateDatabase, LibraryCollectionsDatabase) for download queue, library collections, and recent access history

- Refactor SAF FD handoff in MainActivity: drop detachFd/dup pattern, pass procfs
path to Go and let Go re-open it to avoid fdsan double-close race conditions
- Handle /proc/self/fd/ path in output_fd.go: re-open via O_WRONLY|O_TRUNC instead
of taking raw FD ownership
- Fix Ogg duration/bitrate calculation in audio_metadata.go:
- Use float64 arithmetic and math.Round for accurate duration
- Compute bitrate from file size / float duration at the source
- Validate Ogg page header fields (version, headerType, segment table) to avoid
false positives from payload bytes during backward scan

(Amazon, Qobuz, Tidal, YouTube, extensions) and Flutter download queue
