[architecture] Using free-form natural language for inter-agent communication

Enforce strict JSON schemas \(or Protocol Buffers\) for all machine-to-machine agent messages. Reserve natural language only for the final output to the human user.

Journey Context:
LLMs are probabilistic. If Agent A asks Agent B for data via natural language, Agent B might omit a required field, change the format, or add conversational filler that breaks Agent A's parser. Structured schemas provide a deterministic contract. Agents are just programs; they should communicate via APIs, not chat.
