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

Enforce structured JSON schema for all inter-agent message payloads and handoffs, rejecting any message that fails validation.

Journey Context:
LLMs are unreliable at consistently extracting structured data from free-text across multiple hops. Natural language handoffs seem flexible but inevitably lead to dropped variables or hallucinated parameters. JSON schema enforces a strict contract. Tradeoff: requires upfront schema design and validation overhead, but guarantees state integrity and prevents cascading parsing errors.
