Subject: feat: Add SEO meta tags — canonical and hreflang alternates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Create robots.txt template with Sitemap directive and JSON search index exclusions
- Add canonical link and hreflang alternates (it, en, x-default) to all pages
- Uses Hugo built-ins (.Permalink, .AllTranslations) for production-correct URLs
- All pages now signal canonical URL and language variants to search engines
