fix: sync multiplayer exploration via vote system and fix combat bugs

- Add room vote system for multiplayer exploration (prevents players from independently moving the party to different rooms) - Fix Healer skill targeting: use ally cursor (Shift+Tab) instead of monster cursor, preventing wrong-target or out-of-bounds access - Prevent duplicate action submissions in the same combat turn - Drain stale actions from channel between turns - Block dead players from submitting actions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
