Best Practices

Always pass the correct module references in CommonJS (module and require.main).
For ESM, pass import.meta.url and null for the CommonJS parameters.
Wrap all startup code or CLI logic inside runIfMain to avoid side effects on import.
Use isMain if you need conditional checks without running a function.
