feat: add package.json and package-lock.json for dependency management

- Introduced package.json to define development dependencies for the project, including `oxfmt` and `oxlint`.
- Added package-lock.json to lock the versions of dependencies, ensuring consistent installations across environments.
- Updated sync-readme-tools.mjs to enhance error handling for missing tools table in README.md.
