docs: reconcile docs after ci+website merges; gitignore wrangler/vscode

Post-merge documentation accuracy pass (CI and website branches both
merged to main; website deployed).

- CLAUDE.md: rewrite the stale repository-layout tree; add a Website &
  docs-site decision bullet (Astro+Starlight, Cloudflare Pages via Gitea
  Actions, ADR-website-001, the website branch stays open); update the CI
  note (merged to main; release-macos dispatchable + verified working).
- requirements.md: D1 — macOS targets now runtime-verified (release-macos
  dispatched end-to-end); DOC1 — canonical user docs now live on the
  deployed website.
- ADR-ci-003 (+ docs/ci/adr README): Amendment 2 — CI on main,
  release-macos dispatched + verified; macOS runtime-verified.
- docs/website/adr README: drop the stale "no CI yet".
- .gitignore: ignore .wrangler/ (Cloudflare Wrangler cache) and .vscode/;
  remove the tracked website/.vscode/ an Astro template had added.

D3 (package-manager manifests) + some install instructions remain open.
