Prevent IDLE state and done callback on track replacement mpv emits an end-file event when playback is stopped. During track replacement this caused the media player to transition to IDLE and notify Home Assistant even though a new track was already playing. Introduce a suppression flag to distinguish track replacement from natural playback end and avoid incorrect state transitions.
