- Remove AirPlay from CastProtocol type union (Chromecast only for now)
- Replace AirPlay TODOs with generic 'Future: Add X for other protocols' comments
- Remove PROTOCOL_COLORS export, use hardcoded Chromecast color (#F9AB00)
- Update all component headers to be protocol-agnostic
- Keep switch statements extensible for future protocol additions
- Maintain clean architecture for easy integration of new casting protocols
Architecture remains flexible for future protocols (AirPlay, DLNA, etc.)
