Pull request overview
This PR implements the n/no-path-concat rule from eslint-plugin-n, which disallows string concatenation with __dirname and __filename in Node.js code. The rule helps prevent cross-platform path separator issues by encouraging the use of path.join() or path.resolve() instead of string concatenation.
Changes:
- Added new lint rule implementation for
n/no-path-concatwith comprehensive test coverage - Integrated the rule into the linter's rule registry and generated files
- Added snapshot tests verifying all test cases from the original ESLint plugin
