Disallow `require()` expressions which import private modules (`n/no-unpublished-require`)

💼 This rule is enabled in the following configs: ☑️ flat/recommended, 🟢 flat/recommended-module, ✅ flat/recommended-script, ☑️ recommended, 🟢 recommended-module, ✅ recommended-script.

If a require() expression's target is not published, the program works in local, but will not work after published to npm. This rule disallows require() expressions of unpublished files/modules.

📖 Rule Details

If a source code file satisfies all of the following conditions, the file is *published*.

"files" field of package.json includes the file or "files" field of package.json does not exist.
.npmignore does not include the file.

Then this rule warns require() expressions in *published* files if the require() expression imports *unpublished* files or the packages of devDependencies.

This intends to prevent "Module Not Found" error after npm publish.
💡 If you want to import devDependencies, please write .npmignore or "files" field of package.json.
