• Update CLAUDE.md with full settings key groups, new design patterns (social icon shape, consent banner, mapkit, admin branding, connections page, setup wizard), and corrected command list

What prompted this

Pulled latest main (2 new commits — social icon shape section). Codebase had outpaced docs across several areas: new block type, new admin page, new settings, and the Cloudflare deploy guide needed a dummy-proof rewrite.

Reviewer notes

• All changes are doc-only (.mdx, .md, .json). No code changes.
• cloudflare.mdx is a significant rewrite in length — the old version was ~120 lines, new is ~170 — but content is strictly more accurate and complete.
• connections.mdx is a net-new file; sidebar position is between analytics and contact-form in meta.json.

Test plan

• bun dev:docs → open http://localhost:3002
• Verify Connections appears in the Guide sidebar
• Verify Location appears under Block Types in the Blocks guide
• Verify Cloudflare deploy guide renders all 6 numbered steps cleanly
• Verify WALLET_* section appears in Environment Variables reference
