[architecture] Deadlocks when agents synchronously wait for each other to complete sub-tasks

Design inter-agent communication as asynchronous event-driven workflows rather than synchronous request-response RPCs.

Journey Context:
If Agent A calls Agent B and waits for the response, and Agent B needs context from Agent A \(or another agent\) to proceed, you get a deadlock. This is the multi-agent equivalent of thread starvation. Shifting to an event-driven architecture \(publish/subscribe or state-machine transitions\) means agents emit events and terminate, returning control to an orchestrator. The orchestrator routes the event to the next agent. This guarantees no agent is blocking, though it makes debugging the flow harder as it is non-linear.
