feat: org site with project overview, llms.txt and shortlinks

[raifdmueller]

What

Static org website for https://llm-coding.github.io/, generated by generate.py from the GitHub API.

• index.html: all LLM-Coding repos with GitHub Pages (not archived, without this repo), each with icon, description and link. Readable without JavaScript.
  • The icon comes from the site itself: the largest apple-touch-icon, then rel=icon, then /favicon.ico. It is copied into icons/ at build time.
  • Several sites share the same icon (the docToolchain default on arc42-generator, brownfield-experiment and mistral-vibe), so those icons are dropped and a generated initial is shown instead.
  • Empty repo descriptions are filled from descriptions.yaml. The GitHub description wins as soon as one is set.
  • The URL comes from the Pages API, so custom domains work (ultrathink.club).
• llms.txt: the same list as plain text, plus the shortlinks.
• Shortlinks: each key in links.yaml becomes /<key>/index.html, with a meta refresh, a canonical link and a visible link. sl.html lists them all in a table. The first entry is f → fahrrad-reparatur-architektur. Keys are validated: format, reserved names, collisions with repo page paths, and http(s) targets only.
• Design: plain CSS with light/dark mode, responsive down to 360 px. Version and build date are in the footer (VERSION, now 0.1.0).
• Workflow pages.yml: tests and a build run on PRs. On push to main, daily at 04:17 UTC and manually, it builds and deploys via actions/deploy-pages.

Verification

• 15 pytest tests (network-free)
• Built locally from the live API and checked with Playwright: index (1280 light, 360 dark, no horizontal overflow), sl.html, and /f/, which forwards to the Fahrrad site.

After merge

Pages source must be "GitHub Actions" (see the comment in the PR).
