Improve track title cleaning for comparison

Browse source 
Expanded and refined the noise and version marker removal in _clean_track_title_for_comparison to better normalize track titles. This improves matching by handling more cases such as edits, remasters, live versions, soundtracks, and various collaboration markers.
