Module runtime 

ARCP runtime — the server side of the protocol.

Phase 2 ships:

• server::ARCPRuntime — accepts a Transport, drives the four-step handshake (RFC §8.1), and dispatches subsequent envelopes by exhaustive match on MessageType.
• session::SessionState — tracked per-session bookkeeping.

Job state machines, streams, subscriptions, leases, and artifacts land in Phases 3–5.
