Fix CI: Update c-token references to light-token

Update GitHub Actions workflow and documentation to reference the renamed
light-token directory. The directory was previously renamed from c-token to
light-token, but CI configuration was not updated, causing build failures.

Changes:
- Update rust-tests.yml matrix to use light-token instead of c-token
- Update README.md section heading and directory path
- Update package.json and package-lock.json with new package name
