Pull request overview
This PR implements the import/no-relative-parent-imports rule from eslint-plugin-import, which forbids importing modules from parent directories using relative paths (e.g., ../foo).
Changes:
- Added new linter rule that detects and reports relative imports from parent directories
- Supports ESM imports, CommonJS require(), export declarations, and dynamic imports
- Includes comprehensive test coverage with 16 fail cases and 14 pass cases
