feat(web): marketing landing page with Anthropic design system

Landing page at / matching claude.com/product/claude-code structure:
hero, surfaces, pricing, laptop-to-laptop, features, meets-you, faq, cta,
+ floating "Latest news" toaster. Motion-based scroll reveals.

Design system extracted from claude.com via playwriter reverse-engineering:
- Self-hosted Anthropic Sans/Serif/Mono fonts (6 woff2 files)
- --cm-* tokens in globals.css (clay #d97757, gray-050..900, fluid clamps)
- Serif display, Sans UI, Mono terminals & section markers
- Italic clay phrases for emphasis

Header rewritten for design consistency: claudemesh wordmark (mesh glyph +
serif), dark bg, nav (Docs · Pricing · Changelog · GitHub), "Start free" CTA.

Free-first messaging: hero subhead "Free and open-source. Forever.", primary
CTA "Start free", pricing defaults to Solo=Free.

Fixes:
- packages/api: comment out aiRouter (module removed in 1f094c4)
- packages/db/schema/mesh.ts: rename memberRelations → meshMemberRelations
  (missed in beeaa3b rename pass, caught via web build — ack'd by BotMou)
- credits/{api,server,index}: stub out @turbostarter/ai/credits/utils
- remove (marketing)/legal/[slug] route and common/mdx.tsx (cms-backed)
- sitemap: drop blog/legal enumeration (cms removed)
