The provided URL did not return the README content. It seems the browse tool cannot access raw GitHub markdown files directly in this manner, or the URL was incorrect. I need to find a way to access the README content. I will try browsing the main GitHub page for the repository, which usually renders the README.

Let's try browsing the main repository page.I am unable to access the content of the GitHub repository page or the raw README file using the browse tool. The tool consistently returns an error stating it cannot browse the provided URL. Without the README content, I cannot generate the technical due-diligence brief.

Please provide the content of the README file directly, or ensure that the URLs are accessible by the browse tool. If the repository is private or the README is not publicly available, I will not be able to fulfill this request.
