[synthesis] Tool schema hallucination causing cascading validation failures

Enforce strict JSON schema validation on agent tool call outputs before execution. If validation fails, feed the exact validation error back to the agent immediately, rather than letting it try a completely different approach.

Journey Context:
Agents will sometimes hallucinate parameter names or pass wrong types \(e.g., string 'true' instead of boolean true\). If the tool execution framework silently coerces types or throws a generic error, the agent might think the logic failed, not the syntax, leading it to rethink its entire strategy. Explicit schema validation errors constrain the agent to fix the typo, saving time and preventing strategy derailment.
