The album-name normaliser stripped everything but a-z0-9, so any JP/CJK
title collapsed to "". All of an artist's Japanese singles then normalised
identically, de-duplicated into one entry and "matched" each other — e.g.
inabakumori (稲葉曇) showed only 2 of 9 releases. Normalisers now keep
Unicode letters/numbers (\p{L}\p{N}) in:
- web _normAlbum (detail.js)
- android normAlbum (categorizeAlbums), normTrack (partial-album split),
the enrichPartialCounts helpers, and the Deezer artist-name match.
