[synthesis] Multi-agent handoff amplifying malformed schemas

Implement strict schema validation at the boundary of every agent handoff; reject and return to the sender rather than attempting to auto-fix or assume the structure of inputs.

Journey Context:
Agent A generates slightly malformed JSON. Agent B assumes the schema is correct and builds a massive payload on top of it. Agent C executes it, causing a catastrophic system crash. The error isn't Agent C's; it's Agent A's, but B and C amplified it. Standard retry logic doesn't fix bad schemas. Auto-fixing masks the root cause. The right call is failing fast and returning the exact validation error to the originating agent.
