[architecture] Deadlocks and timeouts from synchronous blocking handoffs between agents

Implement asynchronous, event-driven handoffs where an agent drops a message/event into a queue and terminates its run, rather than waiting for the next agent to respond.

Journey Context:
If Agent A calls Agent B and waits for B's response to continue its own execution, you create a synchronous dependency chain. If B fails or hangs, A hangs. This scales terribly. The correct architectural pattern is event-driven: Agent A emits a TaskCompleted event with the payload, ends its turn, and the orchestrator triggers Agent B. This decouples the agents, allowing independent retries, timeouts, and scaling.
