feat: v1.26.0 — Bulk Select, Song Info, Favorite Button, Recently Played

### Added
- Favorite/Star button in player bar (requested by @halfkey)
- Bulk multi-select for album tracklist and playlist detail (add to playlist, remove from playlist)
- Song Info modal via right-click context menu (metadata: format, bitrate, sample rate, bit depth, channels, file size, path, replay gain)
- Recently Played section on Home page
- "Show activity in Now Playing" opt-in toggle in Settings → Behavior

### Fixed
- Queue cover art not updating on track change (useCachedUrl/CachedImage reset on cacheKey change)
- FullscreenPlayer background flickering (FsBg preloads image before layer transition)
- Playlist card delete confirmation visual (size expansion + pulse animation)
- Gruvbox Light Soft: back button and badge invisible against light background

### Changed
- buildStreamUrl: removed unused suffix parameter
