[frontier] Hardcoding agent-to-agent HTTP endpoints or flat agent swarm with no discovery mechanism

Implement the Google A2A \(Agent-to-Agent\) protocol for capability discovery and task delegation, using Agent Cards for semantic service discovery instead of static URLs.

Journey Context:
Early multi-agent systems hardcoded REST endpoints between agents or used message brokers with no schema. This creates tight coupling; when Agent B moves or scales, Agent A breaks. A2A introduces Agent Cards \(JSON-LD metadata describing capabilities, auth requirements, and endpoint URIs\) that agents fetch from a well-known URL \(\`/.well-known/agent.json\`\). Agents negotiate tasks asynchronously using A2A task objects with Artifacts and Parts, supporting both streaming and push notifications. This replaces direct HTTP calls with a semantic, capability-based discovery layer that scales to dynamic cloud environments.
