BREAKING CHANGE: Merged separate Chromecast and AirPlay implementations into unified casting system
- Created unified casting types and helpers (utils/casting/)
- Built useCasting hook that manages both protocols
- Single CastingMiniPlayer component works with both Chromecast and AirPlay
- Single casting-player modal for full-screen controls
- Protocol-aware UI: Red for Chromecast, Blue for AirPlay
- Shows device type icon (TV for Chromecast, Apple logo for AirPlay)
- Detects active protocol automatically
- Previous separate implementations (ChromecastMiniPlayer, AirPlayMiniPlayer) superseded
Benefits:
- Better UX: One cast button shows all available devices
- Cleaner architecture: Protocol differences abstracted
- Easier maintenance: Single UI codebase
- Protocol-specific logic isolated in adapters
