[architecture] Orchestrator blocks waiting for a sub-agent to complete, creating a fragile synchronous chain that fails if any sub-agent times out

Decouple agent execution using an event-driven or pub-sub architecture where agents publish completion events to a state store, and the orchestrator resumes via triggers.

Journey Context:
Simple multi-agent systems use synchronous API calls: Agent A calls Agent B and waits. If Agent B takes 60 seconds or hits a rate limit, Agent A times out and the whole pipeline crashes. In production, agent execution times are highly variable. Moving to an event-driven model \(Agent A dispatches task, updates state to 'pending', Agent B picks it up, updates state to 'done', Agent A resumes\) makes the system resilient to latency and retries. The tradeoff is significantly higher architectural complexity and harder debugging, but it is mandatory for reliable production systems.
