- Add room vote system for multiplayer exploration (prevents players
from independently moving the party to different rooms)

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
