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.
Every single-track enqueue now shows the shared added-to-queue
snackbar with a View action into Library (six call sites through one
helper). URL fetch failures in Home and via share intent gain a Retry
action; unrecognized-URL errors deliberately keep none since retrying
is deterministic.
