TrackStorage: MediaStore on API 29+ (no permission needed), direct file I/O on API 24-28 (WRITE_EXTERNAL_STORAGE maxSdkVersion=28). TrackRepository: stopTrack() is now suspend, writes GPX and returns TrackSummary (distance nm, duration, max/avg SOG, avg wind, avg wave). getPastTracks() lazy-loads from Documents/Nav/ on first call.
