[frontier] Central supervisor agent becoming a bottleneck and context-overflow point in multi-agent systems

Replace hierarchical supervisors with flat handoff protocols: agents transfer conversation state directly via explicit handoff objects containing full serialized context

Journey Context:
The 'supervisor with sub-agents' pattern collapses under production load because the root LLM's context window fills with aggregated sub-agent outputs, creating a latency sink and single point of failure. Leading teams \(OpenAI Swarm, Anthropic research\) are moving to flat topologies where agents explicitly hand off state to peers. This requires serializable conversation state \(messages \+ working memory\) and clear handoff triggers, but eliminates the root bottleneck and allows O\(n\) scaling instead of O\(tree depth\).
