[architecture] Centralized orchestrator agent becoming a latency and throughput bottleneck because it must process every single inter-agent message

Decentralize point-to-point communication for deterministic tasks using a publish-subscribe or direct message-passing model, reserving the central orchestrator solely for complex, non-deterministic planning and conflict resolution.

Journey Context:
The 'Manager' pattern \(one LLM orchestrating all others\) is easy to build but scales poorly. Every message routes through the orchestrator, doubling latency and token cost. By shifting to a peer-to-peer or pub-sub model for known workflows, agents communicate directly. The orchestrator is only invoked when an agent encounters an unknown state. The tradeoff is that decentralized systems are harder to debug and trace, but they scale horizontally.
