[synthesis] Multi-agent handoffs pass malformed state causing downstream schema violations

Enforce strict JSON Schema validation on all inter-agent handoff payloads, treating agent boundaries like microservice API contracts.

Journey Context:
When Agent A hands off to Agent B, it passes context. If A hallucinates a type change \(e.g., passing string 'null' instead of JSON null\), B rarely crashes immediately. B passes the mutated state to Agent C, who attempts a database write, resulting in a catastrophic schema violation or data corruption. Developers trust agents to maintain type integrity implicitly. The synthesis is applying microservices contract testing to agentic workflows: agents are untrusted clients, and their outputs must be validated against a schema before handoff to prevent silent state mutation.
