Add a selectable Mornye theme with shared glass controls, dialogs, sheets, notifications, and collection headers while retaining Material components.
Update player artwork, lyrics transitions and highlighting, synchronized rolling time labels, volume controls, and compact navigation. Unify metadata, Library, search, and extension surfaces; preserve restored artwork and report extension load failures.
Validation: full Flutter analyzer clean; 713 tests passed and 4 skipped; pinned Dart formatting and diff checks passed; signed ARM64 and ARM32 release APKs built and verified.
The download-time ISRC index now also parses mp3, m4a, ogg, and opus
tags through the existing native readers instead of skipping everything
but .flac. Library settings gain a Review duplicates sheet that groups
history and local-library rows sharing an ISRC via SQL over the
attached databases (no filesystem walk, SAF-safe), shows quality
badges, and offers keep-best and per-copy delete with confirmation.
