Function legacyInterop

legacyInterop(__namedParameters: LegacyInteropOptions): Plugin
Vite plugin that intercepts subpath imports of legacy CJS libraries and wraps them in ESM-compatible virtual modules, preventing CommonJS interop errors at runtime with Rolldown.

Supports nested subpaths (e.g. lib/Grid/Column) and is configurable per library.
Parameters
- __namedParameters: LegacyInteropOptions
Returns Plugin
Example
```
// vite.config.ts
import { defineConfig } from 'vite'
import { legacyInterop } from 'vite-legacy-interop'

export default defineConfig({
  plugins: [
    legacyInterop({
      libs: ['legacy-lib', { name: 'other-legacy-lib', libDir: 'dist' }],
      showLog: true,
    }),
  ],
})
```
