[frontier] Hierarchical multi-agent systems create bottlenecks at manager agents

Implement mesh topologies with gossip protocols using AutoGen 0.4\+ SelectorGroupChat with custom selection functions enabling peer-to-peer agent communication

Journey Context:
Manager-worker hierarchies create single points of failure and communication bottlenecks. The 2025 pattern \(in AutoGen 0.4\+\) uses SelectorGroupChat with custom speaker selection functions that implement gossip protocols—agents share information with neighbors, and state propagates through the mesh via epidemic broadcast. This eliminates the manager bottleneck and improves fault tolerance.
