Report #17145

[architecture] Synchronous multi-agent orchestration blocks the orchestrator while a sub-agent executes a long-running tool, causing timeouts

Use an asynchronous event-driven architecture where agents publish tasks to a queue and subscribe to completion events, rather than blocking on agent.run\(\).

Journey Context:
It is easy to write result = await agent\_b.run\(\) in an orchestrator. But if agent B is running a 5-minute code execution, agent A's context sits idle, burning tokens or timing out. Event-driven pub/sub decouples them. Agent A can handle other requests or terminate until the event fires.
