HoneyandClaude Sonnet 4.6 598c108214 fix: detect YTM artist channel expansion in getYtmVideoUrls; revert PWA MediaSession changes
- ytdlp.js: watch for [youtube:tab] in yt-dlp output during flat-playlist step;
  return [] when channel expansion is detected so cascade falls through to ytsearch
- Revert player.js / main.js / state.js PWA _changingTrack changes (not effective)
