ci: disable Cloudflare Pages deploy; give lychee a root dir

- docs.yml: drop the Cloudflare Pages deploy (hosting is moving to a different
  approach) and park the workflow as manual-only (workflow_dispatch). It now
  just builds the site; CI already validates docs build/examples/prose/links on
  every push. Re-add a deploy step when the new hosting path is decided.
- ci.yml: pass `--root-dir <workspace>/docs` to lychee so root-relative links
  like the kind-banner `<img src="/assets/kinds/*.svg">` (mkdocs serves them
  from the site root = docs/) resolve in offline checking. Fixes the 5 link
  errors in docs/how-to/function-patterns.md.
