Ben 259e78e175 feat(relay): transport protocol + test-only stub connector
Defines RelayTransport (lifecycle/handshake/inbound/outbound/interrupt) as the
gateway<->connector wire contract; RelayAdapter.connect now registers an inbound
handler that bridges connector-delivered MessageEvents into handle_message.
Adds an in-memory StubConnector under tests/ and an E2E round-trip proving:
connect registers the handler, inbound events reach the adapter, guild_id drives
build_session_key isolation (two guilds -> two keys; same guild/channel/user ->
one), outbound send round-trips, get_chat_info is proxied.

Phase 1, Task 1.2 of the gateway-relay plan.

"""End-to-end relay round-trip against the in-memory stub connector.
Proves the gateway side of the relay works with no real connector:
- connect() registers the inbound handler,
- a connector-delivered MessageEvent reaches the adapter's message path,
- SessionSource discriminators (guild_id) drive build_session_key isolation,
- an outbound send round-trips through the transport.
These target the transport contract + session-key derivation (Task 1.2's gate),
not the full agent turn — handle_message is patched to capture the event.
