Fixes oapi-codegen#2091 The `omitempty` JSON tag was not being added to optional nullable fields. The condition `!p.Nullable && shouldOmitEmpty` explicitly prevented any nullable field from receiving `omitempty`, even when the field was optional (not required). This contradicted the documented behavior. The fix removes the `!p.Nullable` guard so nullable fields follow the same `omitempty` rules as non-nullable fields. The special-case exception for the `nullable-type` output option is no longer needed since the logic is now uniform. Note: `x-go-type-skip-optional-pointer: true` on a nullable field suppresses the pointer (generating `string` instead of `*string`) but still correctly receives `omitempty` when the field is optional. Whether skip-optional-pointer should be allowed to suppress the pointer on nullable fields is a separate concern. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
