Subject: Refactor: Convert copy_files.cjs to ES module syntax

- Converted scripts/copy_files.cjs to use ES module syntax (renaming to copy_files.js).
- This change aligns with the project's preference for ES modules over CommonJS for better modernity and future-proofing.
- Updated eslint.config.js to remove the .cjs override.
- Adjusted scripts/build_package.sh to call the new .js file.
