[synthesis] Agent passes deprecated or wrong parameters to tools due to outdated internal schema definitions

Implement automated schema diffing between the agent's tool definitions and the live API's OpenAPI/GraphQL spec, alerting on breaking changes before the agent attempts failing calls.

Journey Context:
Agents are given a static set of tool schemas at deployment. Over time, the downstream API evolves—parameters are renamed, required fields are added, or endpoints are deprecated. The agent might still successfully call the API due to backward compatibility, but it's operating on an outdated mental model, leading to subtly wrong behavior \(e.g., missing a new required flag\). The agent doesn't throw an error, but the quality degrades because the tool's semantics have shifted. Continuous schema validation bridges this gap.
