recv: optional wait_seconds parameter, capped at 60s

Browse source 
AgentRequest::Recv and ManagerRequest::Recv grow an optional
wait_seconds field (default None → 30s, capped at 60s server-side).
agent_server / manager_server clamp via recv_timeout(). MCP tool
schemas advertise the param so claude can pick its own poll window
— useful when an agent wants to throttle wakes without entering a
distinct nap state.

both harness loops still pass None, keeping the existing 30s
default behaviour for system-level Recvs.
