[frontier] How to connect multiple specialized agents without a central orchestrator bottleneck

Adopt the Agent-to-Agent \(A2A\) protocol with Agent Cards for capability discovery; implement mesh topologies where agents negotiate tasks directly via JSON-RPC messages instead of hub-and-spoke

Journey Context:
Centralized orchestrators \(LangGraph central nodes, single supervisor\) become single points of failure and latency sinks as agent counts grow. A2A enables peer-to-peer agent communication with standardized Agent Cards \(JSON metadata describing skills, auth schemes, endpoint URLs\). This supports dynamic mesh topologies where agents can sub-delegate tasks recursively without the parent waiting, enabling true parallel execution and fault isolation. The tradeoff is increased complexity in handling partial failures and retry logic across the mesh.
