[frontier] How to connect agents across different frameworks and vendors

Implement Google A2A protocol for agent discovery and task delegation, using Agent Cards for capability advertisement and Task objects for stateful communication.

Journey Context:
Current multi-agent systems use ad-hoc HTTP/JSON or framework-specific protocols \(LangGraph, CrewAI\), creating vendor lock-in. A2A provides a standardized way for agents to discover each other's capabilities via Agent Cards and delegate tasks with structured inputs/outputs. Unlike MCP which is client-server, A2A is peer-to-peer agent communication. Critical for enterprise agent marketplaces where agents from different vendors must collaborate.
