[synthesis] Multi-agent handoffs corrupt data silently when output schemas drift between agents

Enforce strict, schema-validated message passing between agents using something like JSON Schema. Reject messages with extra or missing fields rather than allowing agents to infer defaults or ignore missing data.

Journey Context:
In multi-agent systems, Agent A might omit a field or slightly change a JSON structure. Agent B, trained to be robust, doesn't fail; it infers a default or ignores the missing data, passing the degraded payload to Agent C. By the time the data is consumed, it is completely corrupted. Human APIs rely on versioning and breaking changes to prevent this, but agents often use flexible parsing. Strict schema validation at the boundary forces immediate failure instead of silent degradation.
