[frontier] Central orchestrator bottleneck in multi-agent systems

Adopt the handoff pattern: each agent can transfer control directly to another agent by returning a handoff object with the target agent name and serialized context, eliminating the need for a central router.

Journey Context:
Central orchestrators create a single point of failure and a scaling bottleneck—every message routes through one agent that must understand all domains. The handoff pattern, as implemented in OpenAI's Swarm framework, lets agents directly delegate to the next appropriate agent. Each agent returns either a final response or a handoff to another agent. Context travels with the handoff as a structured payload. This scales better because no single agent needs global knowledge. The tradeoff: tracing and debugging become harder since there is no single log of all decisions. Mitigate by emitting structured trace events at each handoff. Use central orchestration only when you need strict global ordering or audit trails; use handoffs when agents have clear domain boundaries and can make local routing decisions.
