Bug
Description
iOS WKWebView 音声メモリリーク対策（docs/audio-memory-leak-handoff.md）の続き。 ハンドオフ時点の リークA（シナリオ Luna 音声が endScenarioSession まで解放されない問題）は、SoundManager._scenarioOwnedAliases 集合 + endScenarioSession での _releaseAllScenarioOwnedAliases() 一括解放で セッション単位では解決済み（sound.ts:1853 / :1893 / :1917）。 ただし実機 Safari で Object.keys(window.__pixiSound._sounds) を監視したところ、シナリオ再生中（セッション継続中）はキャラが喋るたびに alias が積み増す ことが確認された。長尺のメインクエスト/イベントだと このリスクは顕著に出てくるため対策を検討する

(これまでの調査内容の共有) ・シナリオを抜けると解放されている。 ・シナリオを抜けるまでは、voice が メモリ蓄積してしまう問題。
