Adds a Guides page that walks a Node server-rendered app from Vercel to a Compute workload: concept map, containerize, Secret, deploy, verify, domain switch, CI, rollback, basic auth, and replacements for Vercel-only features.

Based on the migrate-from-vercel recipe, rewritten against the current Compute, ALB and datumctl pages. It links to existing pages instead of repeating them, and uses commands that exist today (datumctl compute logs, restart, alb hostname add, alb auth set).

• New page: guides/migrate-from-vercel.mdx
• Added to the Guides group in docs.json and to "More tasks" in guides/overview.mdx
• mint broken-links passes

Needs a check before merging

• Rightmost X-Forwarded-For entry is the real client IP (carried over from the recipe, tested once)
• Attaching a hostname takes over the name when Datum runs the domain's DNS
• Non-ASCII header values make Headers.set() throw (framework behavior, from one migration)
• The Astro Dockerfile builds as written
• Vercel-only features table: based on a single Astro and Node migration
• CLA check: PRs from this account should pass, but confirm

The recipe at agents.datum.net/recipes is older than these docs on several points (logs, restart, alb hostname and auth commands). Update it separately so the two agree.
