feat: add GitHub Actions workflow for release builds

- Introduced a new workflow in release.yml to automate the release process for macOS, Windows, and Linux.
- Added a script (update-version.mjs) to update the version in package.json based on the release tag.
- Configured artifact uploads for each platform and ensured proper version extraction and validation.
