fix(build): add webpack config for Node.js module fallbacks

- Configure webpack to exclude fs and path modules from browser builds
- Works with parser's conditional fs import for browser compatibility
- Enables successful Next.js build with parser v1.2.0

This fix allows the website to build while parser retains @include
directive functionality for CLI users.
