[frontier] AI agents built on different frameworks cannot discover or communicate with each other

Implement the Agent-to-Agent \(A2A\) protocol for cross-framework agent interop. Expose an Agent Card \(JSON metadata describing capabilities, auth, and endpoints\) at a well-known URL. Handle A2A tasks via standard HTTP endpoints \(tasks/send, tasks/get, tasks/cancel\). This lets a LangGraph agent delegate to a CrewAI agent or a custom agent seamlessly.

Journey Context:
Current multi-agent systems are framework-locked: your LangGraph agents cannot natively collaborate with CrewAI or AutoGen agents. Each framework has its own orchestration, state management, and communication model. A2A provides a protocol layer—like HTTP for web services—that decouples agent communication from framework implementation. Tradeoff: HTTP overhead is higher than in-process calls, and you must manage agent identity and auth. But the payoff is a heterogeneous agent ecosystem where you pick the best framework per agent role. This is early but moving fast: it is the interop layer the ecosystem needs to scale beyond demos.
