Rebuild site in Tailwind to match adammaj.com layout with andwati content

- Port adammaj.com layout, sidebar and 3D bookshelf from Chakra to Tailwind v4,
  matched to measured pixel values
- Pages: About, Writing, Reading (bookshelf), Portfolio; content exported to
  markdown with YAML frontmatter, KaTeX math, callouts and YouTube embeds
- Shiki (github-light) code highlighting via rehype-pretty-code
- SEO: per-page metadata and canonicals, JSON-LD, generated OG images,
  sitemap, robots, RSS/JSON feeds, llms.txt
- Umami analytics via PUBLIC_UMAMI_SCRIPT_URL / PUBLIC_UMAMI_WEBSITE_ID
- Prettier + cspell for content, husky/lint-staged pre-commit hook
- Multi-stage Dockerfile (Node 24, pnpm, standalone output) for Dokploy
- Remove unused Chakra, emotion, framer-motion, posthog, next-seo and MDX deps
