Website with a feedback form that opens GitHub issues, and pi's contributor gate

- site/: landing page, /feedback/ and /privacy/ on Cloudflare Pages
  (frame-control.pages.dev). POST /api/feedback validates the form and opens
  a labelled issue with a fine-grained token; honeypot, minimum fill time and
  KV rate limits keep spam out. Ko-fi donate buttons appear once the page
  name is set in site/public/js/site.js.
- .github: the issue and PR gate from badlogic/pi-mono. New contributors'
  issues and PRs are auto-closed; a maintainer replying lgtmi/lgtm approves
  them via APPROVED_CONTRIBUTORS. Issue templates and CONTRIBUTING.md.
- CI runs the website tests; README points feedback at the form.
