Greptile Summary

This PR implements solid SEO foundations for the t-req documentation site. It adds canonical URL configuration, comprehensive Open Graph and Twitter Card metadata, and enables prerendering for the homepage to ensure it's included in static outputs.

Key changes:

• Configured canonical site URL in Astro config
• Added global description and social media image tags to Starlight config
• Enhanced Layout component with flexible SEO metadata props (description, OG tags, Twitter Cards, canonical URLs)
• Optimized homepage with keyword-rich title and description, enabled prerendering
• Created robots.txt to allow crawling

Issue found:

• The robots.txt file references a sitemap file, but the sitemap integration is not installed or configured in the project. Without this integration, no sitemap will be generated, which could impact SEO and crawler discovery.

Confidence Score: 3/5

• Safe to merge after fixing sitemap configuration
• The SEO implementation is well-structured and the metadata logic is correct. However, the missing sitemap integration means the robots.txt references a non-existent resource, which should be fixed before merging to avoid 404s for search engine crawlers.
• Pay attention to packages/webdocs/public/robots.txt - needs sitemap integration configured

Important Files Changed

packages/webdocs/public/robots.txt	New robots.txt created but references sitemap that won't be generated without the sitemap integration
