Updated the proxy route to fetch and return the content from
jsdelivr instead of just redirecting to the URL. This change
allows the application to handle and manipulate the content
before sending it to the client, which provides more control
over the data flow.
Introduce a simple Flask app that proxies requests to cdn.jsdelivr.net.
Includes basic routing for home and proxy endpoints, and a template
render for the home page explaining usage. Added Flask to
requirements.txt and updated .gitignore to exclude venv and __pycache__.
