[frontier] Centralized agent orchestrators become bottlenecks and single points of failure in multi-agent systems

Implement decentralized handoff protocols using typed state schemas \(Pydantic v2\) where agents pass conversation state directly to specialized agents via a lightweight router, eliminating the central coordinator

Journey Context:
Early multi-agent systems used a 'supervisor' LLM to route all traffic, which introduced latency \(sequential LLM calls\) and complexity \(the supervisor needed to understand all domains\). The emerging pattern is peer-to-peer handoffs: when Agent A realizes it needs specialized help \(e.g., coding\), it packages the current state \(messages, context, user intent\) into a validated schema and passes it to Agent B, then yields control. This is analogous to OS process scheduling but with typed IPC. The tradeoff is that debugging distributed handoffs is harder than central logs, but it enables horizontal scaling and prevents the supervisor bottleneck. It also aligns with the actor model of concurrency.
