feat/astro migration (#538)
* feat: migrate website from Jekyll to Astro

Rebuilds the site using Astro (SSG) with Tailwind CSS v4, replacing the
Jekyll/Cayman theme. Key changes:

- Splits the monolithic /rules page into 110 statically-generated pages
  (92 per-service + 13 group index + homepage + guide pages) for SEO
- URL structure: /rules/[group-slug]/[service-slug]/ with backward-
  compatibility redirect map for old anchor-based URLs (/rules#redis)
- Modern UI: Prometheus-orange accent, dark mode (system + toggle),
  sticky sidebar, responsive layout, copy-to-clipboard per rule/section
- SEO: per-page <title>, <meta description>, Open Graph, Twitter Card,
  canonical URLs, sitemap.xml via @astrojs/sitemap
- GEO: FAQPage JSON-LD schema on each service page (rules as Q&A pairs
  for AI search engines), TechArticle schema, BreadcrumbList
- Search: Pagefind (build-time index, lazy-loaded, ~200KB)
- Zero JS by default; copy buttons and theme toggle use inline scripts
- New CI: .github/workflows/deploy.yml builds Astro + Pagefind and
  deploys to GitHub Pages via actions/deploy-pages
- Existing dist.yml and test.yml workflows are untouched
- _data/rules.yml remains the single source of truth

Note: GitHub Pages source must be changed from "Build from branch"
(Jekyll) to "GitHub Actions" in repository settings.

* fix: resolve Astro build errors in astro.config.mjs

- Remove assetsInclude yml which caused Vite to treat YAML files as static assets instead of running them through the custom YAML transform plugin; data.groups was undefined at runtime because the import resolved to a URL rather than parsed content
- Deduplicate old-path redirects: emit only the slash-less variant per service to avoid Astro router collision warnings (trailing-slash variant is handled automatically)
