Deploy Summary Integration

This post introduces the Deploy Summary integration, which augments Vercel's GitHub and GitLab integrations. It analyzes pull/merge requests, detects changed pages, and provides detailed previews next to commits. These previews include screenshots, direct links to changed pages, the deployment URL, and the commit SHA. It also introduces the concept of persistent URLs for these previews, which do not change with new commits, simplifying collaboration for projects with login systems.
