[frontier] Multi-agent systems need a central orchestrator agent to route between specialist agents

Replace orchestrator-worker topology with direct agent handoffs: agents transfer full conversation control to the next agent with a context message, eliminating the orchestrator bottleneck entirely.

Journey Context:
The orchestrator pattern \(one boss agent dispatching to workers\) has three critical failure modes in production: \(1\) the orchestrator's context window becomes a bottleneck as it must hold summaries of all worker interactions, \(2\) every round-trip through the orchestrator doubles latency and token cost, \(3\) the orchestrator loses task-specific nuance when summarizing worker outputs for the next worker. The handoff pattern, introduced by OpenAI's Swarm framework, solves this: Agent A transfers control directly to Agent B with a handoff message. Agent B receives the full conversation context, not a summary. This preserves fidelity and eliminates the orchestrator as a single point of failure. Tradeoff: less centralized control makes global guardrails harder. Mitigate by encoding pre-conditions into handoff functions that validate before transferring. Another tradeoff: without an orchestrator, it's harder to enforce that the right agent is active. Mitigate with handoff graphs that define valid transition paths.
