fix(client): address PR #47 review — murmur deferral, zone extraction, 6 tests

Remove premature Voice/VoiceConversation from SOUND_EVENT_ASSETS (D-072 defers murmur to end-to-end sprint). Extract current_zone_id in GameState.apply_snapshot() as first-class field, eliminating O(N) tile scan in main.gd (D-020 server-authoritative). Add dir.list_dir_end() after registry scan. Add rapid zone-crossing + _load_prefs() roundtrip tests. Enhance comments on hub/workplace same-asset pattern, station base hum, and confrontation dip replacement semantics.
