- Skip channel filter when artistFirstWord is non-ASCII (Japanese kanji/kana):
YouTube channels are named in romaji/English, not kanji — the filter was
rejecting all valid results and causing 6+ extra cascade steps
- Add albumQuerySuffix: when title is Japanese (no keyword match) OR has only
one romaji keyword, include the album's first two English words in the search
query so YTM ranks the official OST/album version above fan covers
Fixes: 照井順政 channel filter rejecting all YTM results
Fixes: "Souiunatsu" matching covers with romaji subtitle instead of official OST
