[frontier] Flat agent swarms deadlock or conflict without clear termination logic

Replace flat swarms with hierarchical supervision using structured Command objects for delegation and termination voting, not free-form chat

Journey Context:
CrewAI-style flat swarms \(5 agents negotiating in a room\) fail because no agent has authority to terminate the task, leading to infinite loops \('I disagree, let me check again'\). The 2025 pattern is a strict tree: a Supervisor agent delegates to Child agents using structured output \(Command objects with 'goto', 'update', and 'respond' fields\). Children return structured termination votes \('status: completed/failed/escalate'\). This eliminates string parsing \('FINAL ANSWER:'\) and provides type-safe orchestration. The supervisor maintains a 'state' object that accumulates results, preventing partial overwrite issues. Alternative: DAG-based workflows \(Airflow\) are too static for LLM reasoning chains.
