[frontier] Static manager-worker agent hierarchies create bottlenecks when different workflow phases require different domain leadership

Implement phase-based leadership rotation where the 'manager' role transfers based on workflow phase \(e.g., PM agent leads planning phase → Architect agent leads design → Dev agent leads implementation\), using a shared state thread that persists across leadership transitions

Journey Context:
In multi-agent systems like CrewAI or hierarchical LangGraph, the pattern is usually a fixed manager that delegates to workers. This creates a persistent bottleneck and often mismatches expertise to task phase - a PM shouldn't architect code, an architect shouldn't manage project risk. Leading teams are implementing 'rotating leadership' where the state graph has conditional edges that route to different 'manager' agents based on the current phase flag in shared state. The key insight is that shared state \(the thread\) must outlive any single agent's tenure as leader, and handoffs must explicitly pass control, not just data. This requires structured handoff protocols where the outgoing manager compresses the current state into a 'briefing' for the incoming manager, preventing context overload.
