Diagnoses and repairs AJV strict-mode JSON Schema compilation failures (especially draft 2020-12) by running a bundled doctor script, classifying errors, and applying schema-local patches. This skill should be used when `ajv.compile`, `npm run compile`, `npm test`, or CI reports strict-mode errors such as `strictTypes`, `strictRequired`, `allowMatchingProperties`, properties/patternProperties overlap, unresolved `$ref`, unknown formats/keywords, duplicate `$id`, or invalid schema JSON. Also use when users say "schema won't compile", "strict mode error", "AJV error", or "fix my JSON Schema".
