guides: Phase 2 — Vercel KB landing page + clean content layout

Landing page (layouts/guides/landing.html):
- Remove sidebar filter (checkboxes, language buttons)
- Hero section: guide count, large "Guides." heading, description
- Sticky left "Jump to" nav with numbered categories and counts
- Sections per tag with 2-column card grid (title | summary)
- Scrollspy via IntersectionObserver highlights active section
- No Alpine.js filtering — browse by scrolling/jumping

Content pages (layouts/guides/list.html, new):
- Clean left sidebar: just mainnav, no guide-specific metadata
- Slightly wider article (max-w-5xl)
- TOC stays in right column via baseof.html default

Other:
- data/tags.yaml: add description to each tag (shown under section heading)
- layouts/_partials/guide-languages.html: deleted (languages removed in Phase 1)
- layouts/_partials/sidebar/guides.html: simplify (remove stepper, resource_links,
  languages — now just title, summary, tags, time, back link)
