[frontier] Centralized orchestrator bottlenecks and single points of failure in multi-agent systems

Adopt the Agent2Agent \(A2A\) protocol to enable peer-to-peer task delegation via asynchronous 'tasks' and 'artifacts', eliminating the need for a central orchestrator node.

Journey Context:
Traditional LangGraph or LlamaIndex central nodes create latency and failure points; if the orchestrator dies, the swarm dies. A2A, released by Google in April 2025, defines a JSON-RPC protocol where agents expose 'Agent Cards' advertising capabilities. Agents create 'Tasks' that are passed directly to peers, with 'Artifacts' \(content-addressable handles\) flowing between them. This enables mesh topologies where control is distributed, and agents can recursively delegate without central coordination, crucial for resilient production swarms that must survive individual node failures.
