Migrate canonical domain from braboj.me to codewithbranko.com

[braboj]

What

When codewithbranko.com is set up, migrate the tutorial's canonical domain from braboj.me to codewithbranko.com.

Steps

1. Set up codewithbranko.com with GitHub Pages (or other hosting)
2. Update site in astro-site/astro.config.mjs to https://codewithbranko.com
3. Update robots.txt sitemap URL
4. Set up 301 redirects from braboj.me/tutorial-git/ to codewithbranko.com/tutorial-git/
5. Update Google Search Console — add codewithbranko.com property, submit sitemap
6. Update all external links (Dev.to, Hashnode, LinkedIn, GitHub repo description)

Why

codewithbranko.com is the tutorial brand. Consolidating under one domain builds SEO authority for all tutorials (Git, Azure, Python).
