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
- Extract collectLibraryAudioFiles() and applyDefaultLibraryMetadata() in Go library_scan.go
- Extract plainTextLyricsLines() in Go lyrics.go, used by Apple Music, Musixmatch, and QQ Music clients
- Add configurable SongLink region (userCountry) setting with picker UI
- Pass songLinkRegion through download request payload to Go backend
- Go backend: thread-safe global SongLink region with per-request override
- Fix downloaded track not recognized in collection tap: add findByTrackAndArtist
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
- Replace batch Share action with batch Re-enrich in local album selection bar
- Full native/FFmpeg re-enrich flow with SAF write-back support
- Triggers incremental local library scan after completion to refresh metadata
- Queue tab: switch first selection action to Re-enrich when all selected items are local-only
- 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
- Guard against corrupted granule values (>24h duration, <8kbps bitrate)
- Rename trackReEnrich label from 'Re-enrich Metadata' to 'Re-enrich' across all
13 locales and ARB files

with strftime-to-Go layout conversion and robust date parser
- Pass date/release_date metadata to filename builder in all providers
(Amazon, Qobuz, Tidal, YouTube, extensions) and Flutter download queue

cache size and disable overscroll effects for smoother experience
