[frontier] Hierarchical supervisor agents creating throughput bottlenecks

Implement Swarm topology with Handoff objects: stateless agents pass complete context via Handoff messages and terminate, enabling horizontal scaling without persistent supervisor sessions

Journey Context:
LangGraph's supervisor pattern routes all traffic through a central node, creating a bottleneck and single point of failure. OpenAI's 2024-2025 Swarm pattern \(now in production use\) eliminates the persistent supervisor. Instead, agents are stateless functions. When Agent A needs to transfer to Agent B, it returns a Handoff object containing the full conversation state and context. The orchestrator spins up Agent B with this context, and Agent A terminates. This allows any agent to hand off to any other, enabling distributed processing and eliminating the supervisor bottleneck.
