External media controllers (Android Wear, Auto, Bluetooth dashes,
lock-screen widgets) consume the audio_service MediaSession and
silently no-op on any action that isn't in the handler's
systemActions set. Several handler methods were already implemented
but never advertised, plus stop() defaulted to a no-op — which
matched user reports of "media controller on the watch sometimes
works but doesn't play nice with Minstrel."
This patch lines the advertised surface up with what the handler
actually implements + wires a native heart-rating button.
**Expanded controls + systemActions:**
- Added MediaControl.stop to the expanded controls list.
- systemActions now also enumerates stop, skipToQueueItem (override
shipped in v2026.05.13.1), setShuffleMode, setRepeatMode, and
setRating. Without these in the set, Android 13+ drops the
corresponding callbacks from external surfaces.
**stop() override:** halts _player and dismisses the foreground
notification via super.stop(). Default just flipped processingState
to idle without releasing the audio session — external surfaces
treated that as "paused forever".
**setRating wiring (native heart-button protocol):** new LikeBridge
adapter passes through configure() carrying toggleTrackLike +
isTrackLiked closures over LikesController and likedIdsProvider.
- setRating override flips the like through the bridge and re-emits
mediaItem so the watch's heart icon updates immediately.
- _toMediaItem populates MediaItem.rating on every track change so
the right filled/outlined heart shows on track-A → track-B.
- PlayerActions ref.listen on likedIdsProvider calls
refreshCurrentRating so toggling a like from TrackRow / kebab /
another device (SSE) also keeps the watch icon in sync.
**artUri seed on first broadcast:** AlbumCoverCache.peekCached
returns the file path synchronously when the cover is already on
disk. _toMediaItem uses this so warm-cache tracks broadcast with
artUri populated from the first frame — external controllers see
the cover immediately instead of waiting for the later async
_loadArtForCurrentItem path. Cold-cache tracks fall through to that
path unchanged.
