feedback7 R22-VOICES: review fixes — a 选中 tap no longer restarts the battle-voice gap, and the second shop / reward card of one operator says its 选中 line too; the package switch's comment quotes the measured JP size; golden: unchanged

1. VoiceGate.start no longer moves lastAt for VOICE_TAP_SLOTS: a tap still skips the 1.2 s gap but starts none, so a
   部署 / 技能 / 接敌 the battle asks for once after a short 选中 line has ended plays where the last battle line's gap
   ends (a 部署 at 0, a tap at 500: a 作战中 at 1300 was dropped, now plays; inside the 部署 gap it still waits).
2. Shop / reward cards hand only the chess id to the detail, so two cards of one operator (the pool deals duplicates)
   had one 选中 key and the second tap said nothing nor replaced the first line: game.js numbers every card it opens
   (`tap`, cardTap), resolveDetail keeps it, and detailPanel's new selectVoiceKey() includes it (a re-render of the
   same tap keeps its key; pieces / units unchanged). Checked in the mock match: the second card of 歌蕾蒂娅 now calls
   voice() (it made no call on the parent).
3. tools/package.mjs FULL_ZIP_JP_VOICE comment: 89,388,041 bytes = 85.2 MiB on disk, about 76 MB zipped (as ASSETS /
   DEPLOY), not "~93 MB, barely compresses".
Tests: test/ui/audio.test.js (the tap-gap case; one earlier assertion that encoded the old gap after a tap replaced),
test/feedback7-voices.test.js (new: the card tap in resolveDetail / selectVoiceKey / game.js) — both fail on the parent.
§21.30's 0.2.2 note updated.
