Description

Hi, the current version of @hey-api/openapi-ts in this project is outdated. Could we upgrade it to the latest version?
The new version brings important improvements including plugin-based architecture, better OpenAPI 3.1 support, and various bug fixes. There are some breaking changes (config format, client package separation, generated code structure) that will need to be addressed during the upgrade.
Would be great to have this updated. Happy to help if needed!
