v4.8.2

What's Changed

• YouTube playback now prefers the video's original audio track on videos that have auto-dubbed or multi-language audio. YouTube flags the track matching the request language as default, so English AI dubs were being played instead of the original. Applies to both the direct URL and SABR playback paths.
• YouTube: empty strings in track metadata and parsed JSON are treated as missing instead of blank values.
