📚 Description

When exporting a validator from a package using vine.union.if the compilation fails with error:

- error TS2742: The inferred type of 'myValidator' cannot be named without a reference to '../../node_modules/@vinejs/vine/build/src/schema/union/conditional.js'. This is likely not por │ table. A type annotation is necessary.

Exporting UnionConditional fixes this issue.
