- Replaces the rsync command in the build_package.sh script with a
Node.js script (copy_files.cjs) to handle copying necessary files
(e.g., .md, .json, .sb) during the build process.
- Addresses an issue where the build would fail on systems
that do not have rsync installed (e.g., some Windows environments or
minimal Linux distributions) by using a Node.js script, providing a
cross-platform solution as Node.js is already a project dependency.
- Updates the ESLint configuration to correctly lint .cjs files as
CommonJS modules.
