Report #40746

[architecture] Waiting for sub-agents to complete sequentially when tasks are independent, causing massive latency

Map out dependency graphs and execute independent agents asynchronously \(e.g., using asyncio.gather or Map-Reduce patterns\), merging their results in a subsequent aggregation step.

Journey Context:
It is easy to write agent code that calls agent\_a.run\(\), waits for the result, then calls agent\_b.run\(\). If A and B don't depend on each other's output, this is pure latency waste. Parallel execution requires thinking about the agent workflow as a Directed Acyclic Graph \(DAG\) rather than a simple sequential script.
