Add Oxlint configuration and integrate linting commands

- Introduced a new `.oxlintrc.json` file to configure Oxlint for code quality checks.
- Updated `package.json` to include linting scripts (`lint` and `lint:fix`) for easier code maintenance.
- Enhanced documentation in `README` files to guide users on running Oxlint checks and applying fixes.
