feat: wire NSBridge fully + HD artwork + disable watchdog in wrapper mode

player.js
- Replace `_native()` function with `const HAS_BRIDGE` (evaluated once at
  module load so bridge detection is rock-solid)
- Add `buildTrackList()` — maps S.queue to NSBridge Track array with 1024px
  artworkUrl so lock-screen cover is crisp on high-DPR displays
- Add `_pushQueueIfBridge()` — called by `fillRadioQueue()` so radio top-ups
  are pushed to ExoPlayer in real time (fixes autoplay gap after radio refill)
- `playQueue`: route through `NSBridge.setQueue` when bridge present; old
  `S.audio` path retained for browser/PWA fallback
- `playCurrent`: `NSBridge.seekToIndex + play` in bridge mode
- `nextSong / prevSong / togglePlay / onEnded`: delegate to bridge, skip local
  S.qIdx manipulation (native sends onTrackChanged callback instead)
- `seekTo / _initBarScrub`: use `_lastDurationMs` for ms-accurate seeks
- `onTrackChanged`: guard with `p.index !== S.qIdx` to avoid redundant redraws
- `updateMediaSession`: artwork sizes 96/300/512 → 256/512/1024
- Player-bar cover: 100 → 256px; NP cover/bg: 400 → 1024px;
  queue items: 60 → 128px; preload hint sizes: 96/300/512 → 256/512/1024

main.js
- Wrap watchdog setInterval in `typeof window.NSBridge === 'undefined'` guard;
  the foreground service keeps ExoPlayer alive — JS watchdog not needed there

views.js
- Album detail / playlist detail covers: 300 → 512px
- Playlist grid cards: 200 → 512px
- Search result song cards: 200 → 256px
- Artist top-songs / all-songs thumbnails: 60 → 128px
- Partial album art in _renderArtistAlbums: 300 → 512px

components.js
- makeAlbumCard: 200 → 512px
- makeSongItem: 60 → 128px

nowplaying.js
- NP queue items: 60 → 128px
- NP action sheet thumb: 80 → 256px

sw.js
- Bump CACHE to ns-v41 so stale small-cover entries are evicted on next load
