Room Protocol

The protocol specification between a room instance and the game client, after the client resolves the room through Discovery.

Phases

1. Well-known: the client discovers the room's capabilities (/.well-known/game-room).
2. Handshake: session agreement, with an ECDH key unique to each client.
3. Schema: the room defines the format of the $.server, $.me, and $.others dictionaries.
4. State sync: reactive state exchange, with caching by _id and ttl_ms.
