[frontier] Central orchestrator agent becomes bottleneck and single point of failure in multi-agent systems

Replace central orchestrator with handoff-based delegation. Each agent is autonomous with its own instructions and tools. Agents transfer control to other agents via structured handoff messages that include full conversation context. No agent 'owns' the workflow—control flows to whichever agent is most appropriate at each step.

Journey Context:
The central orchestrator pattern \(one 'brain' agent routing to worker agents\) is the first pattern most teams try. It works for 2-3 agent systems but breaks down at scale: the orchestrator's context overflows from holding all conversation state, it becomes a single point of failure, and every new agent capability requires orchestrator prompt updates. The handoff pattern inverts this: agents are peers, and control transfers between them. The critical implementation detail: handoffs must transfer FULL conversation context, not just a summary, or the receiving agent loses situational awareness. Tradeoff: less global visibility into workflow state, but better scalability, simpler individual agents, and no orchestrator bottleneck. Add a lightweight observer for logging/audit if needed.
