Delete the entire Qobuz downloader implementation (qobuz.go, qobuz_test.go)
including all API clients, search, metadata, download, and track matching
code. Empty the builtInProviderRegistry now that all built-in providers are
retired. Remove Qobuz-specific exports (SearchQobuzAll, GetQobuzMetadata,
ParseQobuzURLExport) and the downloadWithBuiltInQobuz adapter. Stub out
PreWarmTrackCache and cache management since no built-in providers remain.
Move qobuz cover upgrade regex to cover.go. Update Dart screens, providers,
and localization strings for the provider-agnostic UI.
Add set/get/clear store registry URL method channel handlers on Android,
iOS, and Go backend so users can configure a custom extension repository.
Store tab now shows a setup screen when no registry URL is configured,
with a cleaner layout (removed redundant description and helper text)
and visible TextField borders for dark theme.
Minor comment and formatting cleanups across several files.
- Add PopScope with canPop:true to all settings pages for predictive back gesture support
- Change settings navigation to use PageRouteBuilder instead of MaterialPageRoute
- Add album folder structure setting (artist_album vs album_only)
- Fix extension search result parsing to handle both array and object formats
- Update CHANGELOG
Fixes back gesture freeze issue on OnePlus and other Android 13+ devices with gesture navigation
