[architecture] Coordinator agent blocks waiting for a sub-agent's response, freezing the system or timing out

Design agent coordination as asynchronous event-driven workflows \(task queues\) rather than synchronous RPC calls.

Journey Context:
LLM inference is slow and variable. Synchronous RPC-style coordination \(Agent A calls Agent B and waits\) leads to thread starvation and timeout cascades. If Agent B hangs, Agent A hangs, and the coordinator hangs. Asynchronous task dispatch with state updates allows the system to remain responsive. Tradeoff: Async workflows are significantly harder to debug and trace than synchronous call stacks. Implementing distributed tracing across agent handoffs becomes mandatory to reconstruct the execution path.
