require() issue in next projects

This file is being treated as an ES module because it has a '.js' file extension and '\web-llm\examples\next-simple-chat\node_modules\@mlc-ai\web-llm\package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

This error has been reported in various issues:

• #140
• #353
  • The error in this issue for some reason stems from web-tokenizer rather than web-llm (though the _scriptDir part is indeed from web-tokenizer)
• #383

Revisit after the following PR is merged and npm is updated, should be able to resolve all issues above:

• #397

perf_hooks issue

This error is reported in issues:

• #127
• #258
