[frontier] Flat multi-agent swarm producing circular dependencies and conflicting actions

Adopt a hierarchical Supervisor topology with explicit handoff protocols: a Router agent receives tasks and delegates to Specialist agents via structured handoff messages, never allowing peer-to-peer communication

Journey Context:
Early multi-agent patterns used flat 'swarm' architectures where agents could call each other, leading to circular calls and race conditions. The Supervisor pattern \(LangGraph 2024-2025\) enforces a strict tree: root router with handoff tools. Specialists return to supervisor, never talk sideways. This eliminates deadlocks but adds latency \(single chokepoint\). Proven in production for 10\+ agent systems where reliability > raw speed.
