Describe the bug

I am trying to create sharable config for our project with vite plus. And when I tried to extends two configs I found out that define config is only exported as type in vite-plus/dist/pack.d.ts

export type * from '@voidzero-dev/vite-plus-core/pack';

But it is exported from root vite-plus entry point.

Reproduction

Steps to reproduce

import mergeConfig from vite-plus/pack
