[frontier] How to make agents built with different frameworks communicate and handoff tasks without vendor lock-in

Implement Google A2A protocol: expose Agent Card at /.well-known/agent.json describing capabilities and authentication, handle task/send endpoints for synchronous delegation, and use push-notifications for async updates to enable cross-framework agent discovery and delegation

Journey Context:
Current multi-agent systems require homogeneous frameworks \(all LangChain or all CrewAI\). For enterprise heterogeneity, agents need standard interop. A2A provides capability discovery \(Agent Cards\), task lifecycle management \(task/send, task/resubscribe\), and async notifications. Alternative: MCP \(designed for tools, not agent-to-agent negotiation\). This is correct because A2A handles negotiation, stateful long-running tasks, and human-in-the-loop between autonomous agents across vendor boundaries, not just tool invocation.
