[frontier] Flat agent swarms hitting O\(n²\) communication overhead and consensus failures in production

Implement tree-structured hierarchies with explicit handoff protocols where manager agents delegate to workers and return final answers up the tree, isolating failure domains

Journey Context:
Flat swarms \(every agent talks to every other\) scale poorly beyond 3-4 agents, creating message storms and circular dependencies. Hierarchies reduce latency and isolate failures. The critical insight is that handoffs must pass immutable context bags, not shared state references, to prevent side effects when sub-agents fail. Alternatives like pub/sub buses introduce eventual consistency issues that are harder to debug than explicit tree hierarchies.
