[architecture] Agents failing to parse instructions or hallucinating parameters when handing off context via natural language

Enforce structured JSON schemas for all inter-agent handoffs and state transfers. Use natural language only for final user-facing outputs.

Journey Context:
LLMs are unreliable consumers of free-text generated by other LLMs; they often ignore constraints or hallucinate missing fields. A structured schema acts as a rigid contract between agents, ensuring the receiving agent gets exactly the typed, validated data it expects, reducing parsing errors and token waste.
