[research] Agent breaks after minor updates to external API or tool schemas

Implement schema-diff regression tests. Store the JSON schema of tools used in your golden eval dataset, and run a CI check to diff the current live API schema against the golden schema before agent runs.

Journey Context:
Agents are highly sensitive to tool descriptions and schemas. A vendor adding a required field or changing a description can silently break the agent's ability to format arguments. Evaluating only the agent's logic misses external schema drift. By diffing schemas in CI, you catch breaking changes before the agent even runs, preventing silent argument-hallucination failures.
