[architecture] Unstructured text handoffs between agents cause cascading parsing failures

Enforce strict JSON Schema contracts at agent boundaries using structured output generation and validate the payload \*before\* the receiving agent processes it.

Journey Context:
Developers often treat agents like humans, passing free-text context. This works until Agent B expects a specific format \(like a list of IDs\) and Agent A outputs prose. Unstructured handoffs lead to brittle regex parsing in Agent B. By enforcing a JSON Schema contract at the boundary, the orchestrator can catch format errors immediately and retry Agent A, rather than letting Agent B hallucinate on malformed input. The tradeoff is slightly higher token usage and latency for structured generation, but it eliminates an entire class of state-parsing bugs.
