feat(web): update landing page copy for full feature surface, add getting started + mesh vs MCP

Landing page copy was stuck at the v0.1 feature set (messaging + state + memory + groups).
The CLI now ships 43 MCP tools across 5 persistence backends. This commit brings the site
copy in sync with what's actually built.

Changes:
- Hero, features, pricing, FAQ, CTA, footer: reflect 43 tools, files, SQL, vectors, graphs
- Features section: expanded from 4 tabs to 7 (added Files, Database, Vectors)
- New /getting-started page: full install guide with correct 4-step flow
- New Mesh vs MCP section: side-by-side diagrams + 8-row comparison table
- Fix: install-toggle on /join page had `npx claudemesh@latest init` (init doesn't exist)
  → replaced with `curl -fsSL https://claudemesh.com/install | bash`
- Navigation: added Getting Started to header, footer, hero link
- COPY.md synced with all 6 capability areas
