Note

Fixes response format detection when responses use $ref, resulting in proper "json" format in generated requests; adds test coverage and updates snapshots.

• Core
  • Update src/schema-routes/schema-routes.ts to pass contentTypes into getRequestInfoTypes, ensuring correct contentKind/format resolution for $ref-based responses.
• Tests
  • Add tests/spec/extractResponseRef/basic.test.ts and tests/spec/extractResponseRef/schema.json with snapshot tests/spec/extractResponseRef/__snapshots__/basic.test.ts.snap.
  • Refresh snapshots across projects to reflect explicit format: "json" in generated requests.
• Release
  • Add changeset (.changeset/stale-masks-hug.md) for a patch bump of swagger-typescript-api.
