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

Enforce structured-schema \(JSON\) messaging for all inter-agent communication; reserve natural language strictly for the final user-facing output.

Journey Context:
Developers often let agents 'talk' via natural language because it mimics human teams. However, LLMs are unreliable at consistently extracting structured parameters from unstructured text, leading to cascading parsing errors downstream. Structured schemas act as an API contract between agents, eliminating extraction hallucinations and making the system deterministic at the integration boundaries.
