Describe the bug

When @module-federation/dts-plugin is executed in an ESM context (e.g. Node.js workers, direct execution with "type": "module"), it throws:

import fse, { ensureDirSync, existsSync, writeFileSync } from "fs-extra";
                             ^^^^^^^^^^
SyntaxError: Named export 'existsSync' not found. The requested module 'fs-extra' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'fs-extra';
const { ensureDirSync, existsSync, writeFileSync } = pkg;

Reproduce

• @module-federation/vite 1.12.0
• ESM module resolution
