Lint an OpenAPI spec and diff two versions to catch breaking API changes before they reach consumers.

Across two versions it flags removed paths and operations, removed response codes, a parameter becoming required, narrowed parameter types, removed enum values, and removed response fields. Analyzes JSON specs (convert YAML to JSON first).
