Report #55539

[frontier] Flat agent swarms failing at scale due to O\(n²\) coordination overhead

Implement tree-structured agent hierarchies with dynamic leader election using AutoGen v0.4 Core API nested teams pattern

Journey Context:
Production systems hit coordination collapse at 10\+ agents. Flat architectures create message storms. Hierarchical delegation reduces overhead to O\(log n\) by treating teams as atomic units with elected leaders managing subordinate agents.
