[architecture] Orchestrator thread blocking while waiting for a long-running sub-agent to complete, stalling the entire pipeline

Implement an event-driven architecture using durable execution or message queues where sub-agents publish completion events, allowing the orchestrator to suspend and resume statefully.

Journey Context:
Naive multi-agent frameworks use direct, synchronous function calls for agent execution. If the 'Research Agent' takes 5 minutes to scrape and synthesize data, the orchestrator thread hangs, consuming resources and failing to handle other user requests. By adopting an event-driven or durable execution model \(like a workflow engine\), the orchestrator can suspend its state, free up resources, and resume only when the sub-agent publishes a completion event. This trades implementation complexity for massive scalability and resource efficiency.
