Detects JavaScript resources that return 3XX redirects

## Solution

JavaScript files that redirect add unnecessary latency and increase page load time. Update script src attributes to point directly to the final URL. Common causes: CDN URL changes, versioned script paths, or domain migrations. Check if third-party scripts have updated their recommended URLs.
