Resolve API (api.zarz.moe):
- Refactor songlink.go: Spotify URLs use resolve API, non-Spotify uses SongLink API
- Add SongLink fallback when resolve API fails for Spotify (two-layer resilience)
- Remove dead code: page parser, XOR-obfuscated keys, legacy helpers
Multi-artist tag fix (#288):
- Add RewriteSplitArtistTags() in Go to rewrite ARTIST/ALBUMARTIST as split Vorbis comments
- Wire method channel handler in Android (MainActivity.kt) and iOS (AppDelegate.swift)
- Add PlatformBridge.rewriteSplitArtistTags() in Dart
- Call native FLAC rewriter after FFmpeg embed when split_vorbis mode is active
- Extract deezerTrackArtistDisplay() helper to use Contributors in album/playlist tracks
Code cleanup:
- Remove unused imports, dead code, and redundant comments across Go and Dart
- Fix build: remove stale getQobuzDebugKey() reference in deezer_download.go
Third-party extensions (e.g. Spotify PKCE addons) need three things the current app does not fully provide:
Extension button results – The Go runtime returned { success, result: { message, open_auth_url, … } } while Flutter read message / open_auth_url only on the outer map, so OAuth buttons appeared to do nothing. InvokeAction now merges the extension’s return object onto the top-level JSON (arrays/non-objects still use result).
Flutter – extension_detail_page: unwrap nested result for compatibility, merge setting_updates into saved extension settings (for copyable OAuth URLs), and launchUrl when open_auth_url is set.
Mobile OAuth return – spotiflac://callback?code=…&state=<extension_id> was not handled on Android (manifest + MainActivity) or iOS (AppDelegate open URL + cold-start launchOptions). This wires SetExtensionAuthCodeByID + invokeExtensionAction(..., "completeSpotifyLogin") so PKCE extensions can finish login after the browser redirect.
Extension store HTTP – Add Cache-Control: no-cache on registry and extension package downloads to reduce stale CDN/proxy responses.
Testing: Install a metadata extension that uses PKCE; tap Connect; confirm browser opens, return via spotiflac://callback, and tokens complete without pasting the code manually.
extension InvokeAction JSON was nested under result while the Flutter settings UI only read the top level, so OAuth-related buttons never showed messages or opened the browser. This PR flattens that payload, merges optional setting_updates, launches open_auth_url, adds spotiflac://callback handling on Android and iOS, and sends no-cache on store HTTP fetches. Needed for extensions like SpoitiLists (Spotify Web API + PKCE).
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 Set-based O(1) track containment checks for wishlist, loved, and playlist tracks
- Add batch addTracksToPlaylist with PlaylistAddBatchResult
- Go backend: strict mode locks download to selected provider when auto fallback is off
- Go backend: fix extension progress normalization (percent/100) and lifecycle tracking
- Go backend: case-insensitive provider ID matching throughout fallback chain
- Lyrics embedding now respects lyricsMode setting (embed/both/off)
- Debounced queue persistence to reduce write frequency
- Fix shouldUseFallback logic to not be gated by useExtensions
