This release adds support for user-generated content (UGC) downloads and ReplayGain volume normalization.

✨ What's New

• UGC track downloads — Download user-uploaded tracks to an _Unofficial/ folder with Artist - Title [videoId] naming (#22)
  • Enable with YUBAL_DOWNLOAD_UGC=true (off by default — UGC tracks are still skipped unless enabled)
• ReplayGain tagging — Automatic volume normalization via rsgain for consistent playback levels (#49)
• Unmatched track routing — Tracks that don't match an album are saved to _Unmatched/ instead of being skipped (#32)
• Mid-download cancellation — Cancel running downloads immediately via yt-dlp progress hooks instead of waiting for the current track to finish
• ASCII filename transliteration — Add back option to transliterate unicode filenames to ASCII via unidecode with YUBAL_ASCII_FILENAMES=true (off by default) (#58)

🔧 Improvements

• CLI documentation — Added README with install and usage docs
• _Playlists/ folder sorting — Renamed Playlists/ to _Playlists/ for top-sorted directory listing, to align with the introduced _Unmatched/ and _Unofficial/ folders.

🐛 Bug Fixes

• Fixed cookies being invalidated after being used by yt-dlp
