[architecture] Agents hallucinate parameters when parsing free-form text messages from other agents

Enforce structured JSON schema for all inter-agent communication; reserve natural language exclusively for the final user-facing output.

Journey Context:
Developers default to natural language for agent-to-agent chat because LLMs excel at it. However, LLMs are unreliable at extracting precise parameters from paragraphs without dropping details or hallucinating constraints. Free-form seems flexible but causes cascading parsing errors. Structured schemas enforce a strict contract, making state transfer deterministic and debugging tractable.
