- Added LICENSE.txt file for JavaScript assets in the build directory, including licenses for NProgress and React libraries.
- Introduced a new runtime JavaScript file for handling module loading.
- Created a new DocItem component to manage document rendering and metadata handling in the Docusaurus theme.
- Implemented tests for the docs proxy server to ensure proper routing to the configured docsPort.
