[frontier] Agents communicating via natural language suffer from parsing errors and ambiguity

Enforce JSON Schema contracts \(A2A protocol style\) for inter-agent messages with explicit capability advertisements via Agent Cards

Journey Context:
Early multi-agent systems used natural language between agents, causing endless regex parsing bugs and semantic drift. The A2A \(Agent-to-Agent\) protocol defines structured Artifact and Task objects instead of free text. Agents advertise capabilities via Agent Cards \(JSON metadata\). This is like gRPC for agents versus REST\+text. It eliminates ambiguity but requires strict schema governance and reduces flexibility for emergent communication.
