Report #71295

[architecture] Running independent agent tasks sequentially, unnecessarily increasing latency

Fan-out independent sub-tasks to parallel agents, then fan-in to aggregate results. Use a map-reduce pattern for independent data gathering or transformation.

Journey Context:
Sequential execution is easier to debug but wastes time. If agents do not share mutable state during their execution phase, they can run concurrently. The orchestrator must handle the fan-in and aggregation to synthesize the final result.
