site: remove the unproven remote claim from the Nook landing page

FRE-323. The one-click remote install is app-UI-only and needs hand-edited ~/.ssh/config plus a one-time ssh-copy-id (FRE-320); FRE-315 and FRE-322 hold the claim unverified and demo-gated.

- drop the Remote tile and its mock from the feature collage
- drop the "Any SSH box, one click away" breakdown, its demo and bullets
- drop "Works across every hooked agent, local or remote"
- drop the "One-click SSH setup" chip
- move the copy to marketing/drafts/remote-ssh/ and mark remote held in marketing/positioning.md

No replacement claim was added. Deploy waits on a push credential for the GitHub repo Vercel builds.
