[frontier] Multi-agent orchestrator becomes a bottleneck and single point of failure in production

Replace the orchestrator-worker topology with handoff-based delegation. Each agent can transfer control to any other agent by returning a handoff object containing the target agent and a context message. No single agent routes all traffic.

Journey Context:
The orchestrator-worker pattern \(one central agent dispatches tasks to specialist workers\) is the intuitive first design for multi-agent systems. In production, the orchestrator becomes a bottleneck: it must parse every request, understand all capabilities, and route correctly. It also becomes a single point of failure. The handoff pattern, introduced in OpenAI Swarm, inverts this: every agent is an entry point, and agents transfer control by returning a handoff to another agent with relevant context. This is like a phone transfer vs. a switchboard operator. Tradeoffs: you lose centralized routing logic \(harder to enforce global policies\), and you need to handle cycles \(agent A hands off to B who hands off back to A\). But you gain resilience, scalability, and simpler agent definitions. The Swarm implementation handles context transfer via function arguments passed during handoff.
