Module protocol 

Wire protocol types for host-renderer communication.

IncomingMessage is deserialized from the host. OutgoingEvent and response types are serialized back. The transport (stdin/stdout, socket, test harness) is handled by the binary crate, not here.

Every wire message carries a session field identifying the logical session it belongs to. SessionMessage pairs a session ID with a deserialized IncomingMessage. All outgoing types include a session field that echoes the originating session ID back.
