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

Replace orchestrator-worker topology with agent handoffs. Each agent exposes a handoff tool that transfers full conversation control to another agent. The receiving agent inherits the entire conversation history and continues autonomously. No central dispatcher. No round-trip through a boss agent.

Journey Context:
The orchestrator-worker pattern \(one boss agent dispatching to specialist workers\) seems natural but fails at scale: the orchestrator becomes a latency bottleneck, context gets lost in translation between orchestrator and worker, and the orchestrator's context window overflows from accumulating all sub-task results. The handoff pattern, where agents directly transfer control to each other, is simpler and more robust. It trades centralized observability for emergent coordination, but in practice most multi-agent tasks don't need a central brain — they need specialists who know when to hand off. The critical implementation detail: the handoff function must transfer the FULL conversation history, not just a summary, so the receiving agent has complete context. OpenAI's Swarm framework demonstrated this as a minimal primitive — the entire framework is essentially agents \+ handoffs \+ context variables, nothing more.
