Report #7347

[architecture] Orchestrator waiting synchronously for a sub-agent to complete a long-running task, blocking the pipeline and timing out

Use an event-driven or asynchronous architecture where agents publish results to a topic or state queue when done, rather than blocking the orchestrator thread.

Journey Context:
Multi-agent systems often look like simple RPC calls. But LLM inference plus tool execution can take minutes. Blocking wastes resources and hits HTTP timeouts. The tradeoff is architectural complexity \(async state management\) vs. resilience and throughput.
