- downloadQueueLookupProvider now reads pre-computed lookup from state directly

- Default track/disc number to 0 (unknown) instead of 1, letting the
backend use the service-provided value or skip the field entirely
- Add releaseDate to ExploreItem so explore downloads carry release info
- Pass discNumber and releaseDate from extension album/playlist tracks
- Fix isDeezer detection using service field instead of substring match
- Add _displayServiceTrackId() to properly strip prefixes for all services
ReplayGain (track + album):

Add bytesTotal field to DownloadItem model and show X/Y MB progress
in queue tab when total size is known.
Enable strict-casts, strict-inference, and strict-raw-types in
analysis_options.yaml. Add custom_lint with riverpod_lint. Fix all
resulting type warnings with explicit type parameters and safer casts.
Also improves APK update checker to detect device ABIs for correct
variant selection and fixes Deezer artist name parsing edge case.
Load saved registry URL before first state update to prevent brief
flash of the setup screen when the store tab initializes.
Add Ogg/Opus fallback in readFileMetadata when FLAC parsing fails,
handling files saved with .flac extension that contain opus data.

Requested by @okinaau in issue #242 — brings back the ability to
download tracks in lossy format for users on low storage devices.
HIGH quality fetches the AAC M4A stream directly from the Tidal server
(no lossless download + re-encode), then converts to MP3 or Opus via
FFmpeg based on the tidalHighFormat setting (mp3_320, opus_256, or
opus_128).
- go_backend/tidal.go: restore outputExt .m4a, filename logic,
duplicate-check guard, HIGH M4A lyrics/LRC handling, and
bitDepth=0/sampleRate=44100 for HIGH quality result
- settings.dart + settings.g.dart: re-add tidalHighFormat field
(default mp3_320) with JSON serialization
- settings_provider.dart: re-add setTidalHighFormat(), remove
migration that force-migrated HIGH to LOSSLESS
- download_queue_provider.dart: restore HIGH conversion logic for
both SAF and non-SAF paths using FFmpegService.convertM4aToLossy
- download_settings_page.dart: restore Lossy 320kbps quality tile,
format sub-picker tile, _getTidalHighFormatLabel helper, and
_showTidalHighFormatPicker bottom sheet
- l10n: add 10 keys (downloadLossy320, downloadLossyFormat,
downloadLossy320Format, downloadLossy320FormatDesc, downloadLossyMp3,
downloadLossyMp3Subtitle, downloadLossyOpus256/Subtitle,
downloadLossyOpus128/Subtitle) to ARB and all 13 generated files
When enabled, playlist downloads are placed inside a subfolder named
after the playlist before the normal folder organization structure
(e.g. Playlist/<artist>/<album>/). The setting is a no-op when folder
organization is already set to 'By Playlist'. Includes model field,
JSON serialization, settings notifier, download queue path logic,
UI toggle in download settings, and localizations for all 13 languages.
- Add dedicated long-timeout download client (24h) for extension file downloads,
preventing timeouts on large lossless audio files
- Skip unnecessary SongLink Deezer prelookup when an extension download provider
handles the track, reducing latency and avoiding spurious API failures
- Prefer native track ID over Spotify ID when a source/provider is set, ensuring
extension providers receive their own IDs correctly
- Update Qobuz MusicDL API endpoint and switch payload URL to open.qobuz.com
- Extract buildQobuzMusicDLPayload helper and add test coverage
- Generate stable SHA-1 based IDs for SAF-scanned library items to prevent null ID crashes on the Dart side
- Suppress false queue-complete notification when user pauses instead of finishing the queue, and break out of parallel loop immediately when paused with no active downloads
- Use SQLite as the single source of truth for library scan results to fix a race condition where auto-scan could fire before provider state finished loading, dropping unchanged rows
The Dart-side _upgradeToMaxQualityCover only handled Spotify CDN
URLs, causing Deezer covers to stay at 1000x1000 and Tidal at
1280x1280. Add regex-based Deezer upgrade (1800x1800) and Tidal
origin resolution upgrade to match the Go backend logic.
Closes#237
When a file is converted externally (e.g. FLAC to OPUS), the
orphan cleanup would delete the history entry because the original
path no longer exists. Now it checks for sibling files with other
audio extensions and updates the stored path instead of deleting.
Also add extension-stripped keys to path_match_keys so that
paths differing only by audio extension still match during local
library scan exclusion and queue deduplication.
Add a new 'Auto Scan' setting under Local Library with four modes:
off, every app open (10min cooldown), daily, and weekly. The app
uses WidgetsBindingObserver to trigger incremental scans on launch
and when resuming from background, respecting the configured
cooldown based on the last scan timestamp.

- Extend _buildTrackForMetadataEmbedding to use ISRC, cover_url, album_artist from backend response
- Add Releases section support in artist page (Go + Flutter)
- Fix Track ID parsing to prefer non-empty native ID over empty spotify_id
- Paginate popular tracks (5 per page with swipe + dot indicators)
