fix(web): re-apply all landing page content fixes (linter reverted)

A linter/formatter reverted our content edits. Re-applying:
- Hero: concrete claims, no WhatsApp/Slack promises, beta pricing
- Logo bar: tech stack instead of fake customer logos
- Pricing: single honest Public Beta tier (removed $12/$24/$99)
- FAQ: real install flow, honest pricing language
- Features: claudemesh.com/install URL
- Toaster: v0.1.4 announcement
- Copy: "volunteers" / "shares" instead of jargon
- Links: #docs → GitHub README, claudemesh.sh → claudemesh.com
