[architecture] Agents hallucinating parameters when passing context via natural language

Enforce structured JSON schema for all inter-agent message payloads instead of free-form text.

Journey Context:
LLMs are unreliable at extracting specific parameters from paragraphs, often dropping required fields or misinterpreting types, which cascades into downstream failures. Free-form chat is fine for user-facing interaction, but machine-to-machine agent communication needs programmatic guarantees. Alternatives like regex parsing of text are brittle. Structured schemas allow validation and fail-fast behavior, ensuring the receiving agent gets exactly the data it needs.
