[frontier] How to prevent message explosion and coordination chaos in multi-agent systems with more than 3 agents

Replace flat P2P topology with a hierarchical Manager-Executor structure: a Manager agent plans and delegates to leaf Executor agents in isolated contexts. State is passed explicitly rather than shared globally. Implement using OpenAI Swarm or AutoGen GroupChat with a Manager agent.

Journey Context:
Fully connected agent topologies suffer from O\(n²\) message complexity and context window overflow as every agent sees every other agent's thoughts. Peer-to-peer delegation leads to circular dependencies. The hierarchical pattern isolates concerns: Managers handle high-level planning and context aggregation, while Executors handle domain-specific tasks with limited context. This mirrors organizational structures and reduces cognitive load per agent. The tradeoff is potential bottleneck at the Manager and increased latency from hierarchical routing. Crucially, Executors must not bypass the Manager to share state, or the topology collapses back to chaos.
