[frontier] Central orchestrator agent routing to worker agents creates bottleneck, single point of failure, and high latency

Implement direct agent-to-agent handoffs where each agent includes routing instructions for when to transfer control to another agent, passing full context. Replace the orchestrator with a lightweight router or eliminate it entirely.

Journey Context:
The orchestrator-worker topology is the natural first architecture for multi-agent systems: one 'smart' agent receives the request, decides which specialist to call, and synthesizes the result. But in production this creates problems: the orchestrator is called on EVERY turn \(expensive\), adds latency, becomes a complexity bottleneck, and is a single point of failure. OpenAI's Swarm pattern demonstrates an alternative: agents hand off directly to each other. Each agent's instructions include 'if the user asks about X, hand off to the X-agent'. The handoff transfers full conversation context. No orchestrator needed for routing. This is lower latency \(one LLM call instead of two for routing\), cheaper \(no orchestrator tax\), and more resilient \(any agent can receive the initial request\). The tradeoff: less centralized control over routing, which requires better observability and testing to ensure agents route correctly.
