[frontier] How to enable interoperability between agents built with different frameworks without tight coupling or custom APIs

Implement the Google Agent-to-Agent \(A2A\) protocol, exposing agent capabilities via JSON-RPC Agent Cards and managing task lifecycles through standardized states \(submitted, working, input-required, completed\) with support for streaming updates

Journey Context:
Previous attempts forced all agents into a single framework or misused MCP for agent-to-agent communication. A2A provides the missing session and task management layer, allowing a CrewAI agent to delegate to a LangGraph agent mid-conversation with explicit handoff contracts and async task updates, solving the interoperability problem without shared state.
