feedback7: merge fb7-voices — the 选中干员 line on every tap (prep / shop / hand, official FOCUS_CHAR: priority 10, cooldown 0, no gap restart), the Japanese voice tree (audio.voiceJp, 2674 files, setting 语音语言 中文 / 日本語, CN fallback), the full zip ships both

- Conflict: public/js/ui/settings.js imports (store from #321 + VOICE_LANGS) — both kept. test/ui/playtest6-elite.test.js's
  source pin of the onDetail line allows the new tap counter (bcee737f).
- Grok review: MERGE AFTER FIXES — the three findings fixed on the branch (bcee737f). Golden unchanged; broad node --test
  5334 (the one failure was that source pin, fixed), i18n strict clean, lint 0 errors, typecheck.
