Report #9561

[architecture] Agents waiting idly for a downstream agent to complete a long-running task, blocking the entire workflow

Use asynchronous event-driven architectures for independent parallel tasks, only synchronizing at defined join points \(barriers\).

Journey Context:
Developers often chain agents sequentially \(A -> B -> C\) because it is easier to reason about. If B takes 30 seconds to research, A and C are idle. Identifying independent tasks and running them concurrently via async dispatch \(like LangGraph's map-reduce or parallel node execution\) drastically reduces latency, though it complicates state merging and error handling at the join point.
