fix: Match Rekordbox XML format exactly - Use compact XML format without line breaks or indentation - Include only TrackID, Name, and Artist attributes for tracks - Use Count attribute instead of Entries for playlists - Set correct Count="4" on ROOT node for playlist count - Remove encoding declaration to match Rekordbox format - Export now 100% compatible with Rekordbox import/export
