Extract primary English alias from MusicBrainz artist data when the canonical name uses non-Latin script (CJK, Cyrillic, etc.). Display it as the primary name in search results and artist detail header, with the native script name as a subtitle beneath. Example: 山下達郎 now shows 'Tatsuro Yamashita' prominently with '山下達郎' as a subtitle. Artists with Latin names are unchanged.
