[frontier] Multi-agent systems cannot interoperate across different frameworks

Implement the Agent-to-Agent \(A2A\) protocol: expose Agent Cards \(JSON metadata of capabilities\) and communicate via standardized Task/Artifact messages over HTTP.

Journey Context:
Agents built with LangGraph, CrewAI, or custom code cannot easily delegate to each other, creating silos. Google's A2A protocol \(2025\) provides a lingua franca: agents advertise capabilities via 'Agent Cards' \(JSON endpoints\) and exchange structured Task objects \(with parts, artifacts, and statuses\). This allows a LangGraph agent to delegate a subtask to a remote CrewAI agent as seamlessly as calling a local tool, enabling heterogeneous multi-agent topologies.
