This commit enables proper Now Playing Info Center integration on iOS, allowing video playback information to appear in Control Center and Lock Screen with working remote controls.
Key changes:
- Activate audio session on app launch with setCategory(.playback, mode: .moviePlayback) and setActive(true)
- Set up remote commands on first play() call instead of during app initialization to avoid claiming Now Playing slot prematurely
- Remove removeTarget(nil) calls that were claiming Now Playing without content
- Enable remote commands (play, pause, toggle, seek) explicitly and add proper target handlers
- Use backend.isPlaying instead of PlayerModel.isPlaying to avoid race conditions
- Include playback rate (1.0 for playing, 0.0 for paused) in Now Playing info
- Update Now Playing info on main queue for thread safety
- Update Now Playing when switching between backends
- Remove audio session deactivation from pause() and stop() methods
Note: This fix works for AVPlayer backend. MPV backend has fundamental incompatibility with iOS Now Playing system.
