Design spec for restructuring the 16-agent hub-and-spoke system into a
layered hierarchy with universal dispatch. Adds Architecture Lead,
Quality Lead (new), and Product Lead tiers. Agents can call each other
directly via the Agent tool with protocol-enforced guardrails: depth-3
limit, loop prevention, cost controls, and structured audit trails.
