Pull request overview

This PR updates the website-next Next.js static-export site to improve docs rendering (including build-time Mermaid), add SEO metadata/routes, and introduce an NGINX-based container/deployment setup.

Changes:

• Render Mermaid diagrams at build time via rehype-mermaid (Playwright/Chromium) and remove client-side Mermaid rendering.
• Add git-backed “last updated” metadata for docs and use it for doc footers + sitemap last-modified timestamps.
• Add robots/sitemap routes and ship an NGINX + Docker setup (including redirect rules and caching headers).
