[frontier] Central orchestrator agent becomes a bottleneck and single point of failure; hard to add new agents dynamically

Implement an Agent Mesh using the A2A \(Agent2Agent\) protocol. Agents advertise capabilities via Agent Cards \(JSON metadata\) and communicate directly in a peer-to-peer fashion. Use transient task contexts rather than persistent central state. New agents join by registering their capabilities to a discovery service \(or gossip protocol\), not by being hardcoded in an orchestrator.

Journey Context:
Multi-agent systems often start with a 'supervisor' pattern where one LLM decides which sub-agent to call. This creates tight coupling and doesn't scale as the number of agents grows \(context window limits on the supervisor\). A2A enables a service-mesh-like architecture for agents, treating them as autonomous services that negotiate task handoffs directly. This supports dynamic coalitions where agents form temporary teams for specific tasks then disband. The complexity is in handling authentication and provenance in peer-to-peer flows, but it eliminates the 'god agent' anti-pattern.
