[frontier] Supervisor-worker agent hierarchies failing as bottlenecks at scale

Replace hierarchical trees with mesh topology using actor-model message passing \(async broadcast/subscribe\) eliminating central coordinators

Journey Context:
Current multi-agent patterns use a 'supervisor' agent delegating to workers. This creates single points of failure, communication bottlenecks \(O\(n\) messages through the supervisor\), and brittleness when the supervisor hallucinates. Mesh topologies treat agents as autonomous actors communicating via message buses \(topics/queues\), similar to Erlang/OTP or Akka. Agents subscribe to relevant topics and broadcast results. This enables emergent coordination without central control. Hard part: achieving consensus on shared state without a central ledger requires distributed data structures or conflict-free replicated data types \(CRDTs\).
