docs(skills): trim design skill descriptions to <=60 chars + inline cross-ref

- claude-design: 'Design one-off HTML artifacts (landing, deck, prototype).' (57)
- popular-web-designs: '54 real design systems (Stripe, Linear, Vercel) as HTML/CSS.' (60)
- design-md: "Author/validate/export Google's DESIGN.md token spec files." (59)

Also adds an inline callout near the top of claude-design pointing to
popular-web-designs and design-md so the cross-reference lands even
without reading the full decision table.

-description: Design-ready operating skill for CLI/API agents creating thoughtful HTML artifacts outside Claude Design's hosted web UI. Use for landing pages, prototypes, UI explorations, decks, component mockups, motion studies, and design-system exercises where the output should be local, self-contained, and high-craft.

 The goal is to preserve Claude Design's useful design behavior and taste while removing hosted-tool plumbing that does not exist in normal agent environments.
 
+**Before starting, check for other web-design skills like `popular-web-designs` (ready-to-paste design systems for Stripe, Linear, Vercel, Notion, etc.) and `design-md` (Google's DESIGN.md token spec format).** If the user wants a known brand's look, load `popular-web-designs` alongside this one and let it supply the visual vocabulary. If the deliverable is a token spec file rather than a rendered artifact, use `design-md` instead. Full decision table below.
