Summary

In #9899, I use default import to import zod to make types clear like below.

But if user use named import in daily development, the types will be emitted like:

And there exists an ast-grep issue when we try to redirect the import path, see ast-grep/ast-grep#1959

Since the named import is the recommended one, so this PR, we use named import to import zod uniformly, and modify the prebundle script to copy the dts file directly instead of using rollup-plugin-dts for bundling to avoid the ast-grep issue and make the types simple and clear.

BTW, zod use namespace and rollup-plugin-dts has some issues for namespace support, so we just use copy when prebundle.
