After MB search + popularity reranking, browse the discographies of
the top 3 artists and fuzzy-match the full query against album titles.
Matching albums not already in results are injected at the front.
Fuzzy matching uses substring containment with word-level ratio
(handles 'for you tatsuro' → 'FOR YOU' at 0.667) and word overlap
as fallback. Threshold: 0.4 ratio.
Example: 'for you tatsuro' now finds FOR YOU by 山下達郎 even though
MB text search treats 'for' and 'you' as stop words and never
returns it. The album is found via Yamashita's cached discography.
