Greptile Summary

This PR fixes footer links that should leave the docs router. The main changes are:

• Adds a root_site mode to docs footer links.
• Renders Blog and FAQ as raw root-site anchors.
• Adds a route test for the Blog and FAQ footer hrefs.

Confidence Score: 5/5

This looks safe to merge after checking the standalone docs deployment path.

• No blocking issues found in the changed code.
• The only follow-up is a deployment-shape check for root /blog/ and /faq/ routes.
