Report #14467

[architecture] Using a synchronous request-response loop for independent sub-tasks, causing massive latency

Map out task dependencies. If tasks are independent \(e.g., code review \+ security scan\), dispatch them asynchronously to parallel agents and use a map-reduce pattern to aggregate results.

Journey Context:
Most agent frameworks default to a sequential, synchronous chat loop \(Agent A calls Agent B, waits, then calls C\). This is simple but creates additive latency. If Agent B and C don't depend on each other, running them sequentially is a waste of user time. The tradeoff is that async orchestration requires a more complex state machine to track pending futures and aggregate structured outputs, but it is strictly necessary for production latency SLAs.
