Add macOS “Now Playing” integration (Control Center & widgets)

[haiGodzilla]

Is your feature request related to a problem? Please describe.
I’m frustrated that YTMDESKTOP2 on macOS doesn’t appear in the “Now Playing” section (in Control Center or the Music Widget). Currently, media playback from the app isn’t recognized by the system-wide media controls, so I can’t see track info, artwork, or control playback outside the app.

Describe the solution you’d like
I’d like YTMDESKTOP2 to integrate with macOS’s native Now Playing APIs (such as the  MPNowPlayingInfoCenter  or the Media Remote framework). This would allow the system to display the currently playing song, album art, and playback controls in the “Now Playing” widget and the lock screen, similar to how the native Music app or Spotify works.

Describe alternatives you’ve considered
I’ve looked into using background services or third-party tools like “BeardedSpice” or “Mac Media Key Forwarder,” but they don’t enable proper integration with the Control Center or widgets. These solutions only intercept media keys, not system-recognized playback metadata.

Additional context
Here’s what I mean:
Other apps (e.g., Spotify, Apple Music, Vox) automatically show their track info in the Now Playing widget.
Adding this would improve the UX for macOS users, making playback control seamless without switching apps.
