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

Enforce strict JSON Schema contracts at agent boundaries; reject the handoff and force a retry if validation fails.

Journey Context:
Developers often let agents output free-text, assuming the next agent's LLM will 'just understand.' This breaks when the receiving agent expects structured data \(e.g., a list of IDs\) to pass to a tool. Unstructured handoffs lead to brittle regex parsing or hallucinated tool calls. By enforcing a JSON Schema at the boundary, the orchestrator can deterministically catch format errors and force the generating agent to retry, isolating the failure before it cascades into an unrecoverable state.
