[frontier] Hardcoding agent endpoints preventing dynamic multi-agent collaboration and capability discovery

Implement Google's A2A protocol allowing agents to advertise capabilities via Agent Cards and negotiate task delegation dynamically rather than static configuration

Journey Context:
MCP connects agents to tools, but agent-to-agent communication in 2025 still uses ad-hoc HTTP. Google's A2A \(April 2025\) standardizes Agent Cards \(JSON metadata describing skills, authentication, endpoints\) and task lifecycle management. Agents discover peers at /.well-known/agent.json and push tasks via the A2A protocol with streaming updates. This replaces brittle point-to-point integrations with dynamic federation. The tradeoff is ecosystem maturity. This is specifically for peer-to-peer agent ecosystems, distinct from MCP's tool-calling model.
