MainViewModel.Trax.cs: music-player state (_musicPlayer/_music/_musicPlaying, TraxIdleBrush), TRAX UI (IsMusicPlaying/TraxError/TraxDotBrush/TraxToolTip), interaction (TraxLeftClick/TraxRightClick/PickTraxTrack), playback (LoadTrax/PlayTrax/PauseTrax/OnTraxPlaybackEnded/RefreshTraxUi), local loopback ducking (UpdateTraxLocalGain). Core keeps the ctor event hookup, LoadLayout/Shutdown/SaveLayoutNow call sites, and Scenes partial's hotkey dispatch. Verify: 0 warnings, 246 passed, 2 known failures only.
