Beeg's API now returns file.id as a number (u64) instead of a string.
The code expected a string, causing all videos to be skipped.
Fixed by accepting both string and numeric file.id values.
Also updated to handle the new signed HLS URL flow:
- Fetch play_url per video to get signed manifest
- Parse key=xxx,end=xxx,limit=xxx/path response format
- Construct HLS URL with required query parameters
- Add Referer header for playback
