fix: race endpoints for download metadata fetching

- GetTrackDownloadInfoAsync now uses RaceAllEndpointsAsync instead of TryWithFallbackAsync
- Prevents sequential fallback through all 10 endpoints on cancellation
- Eliminates cascade of 'task was canceled' warnings
- Consistent racing strategy across all download operations
