Refresh the landing page to reflect the current Gibwork product

Summary

The landing page describes an earlier version of Gibwork: it never mentions the mobile app (live on iOS + Android — Android is at 4.5 stars, 10K+ downloads), never explains how the product actually works (on-chain Solana escrow + non-custodial payouts), omits the Solana Agent Kit integration, and carries stale/templated copy. This PR is a cohesive refresh that brings the page in line with the live product.

What's in it

New sections

• How it works — Post the work -> Talent delivers -> Escrow releases. States the real mechanic: fund in any SPL token, rewards locked in on-chain escrow, released to a non-custodial wallet on approval, building on-chain reputation.
• Now on mobile — App Store + Google Play badges (inline SVG, no new remote assets), app value props, 4.5 stars - 10K+ downloads, and an in-brand device mockup. Includes a Mobile nav anchor + footer badges.
• Built for humans and AI agents — surfaces the Solana Agent Kit integration (agents can post and fund work on-chain), with a docs link.

Copy & content

• Hero positioning rewritten to the live framing; stale "Introducing gibwork" badge replaced with a tappable "Now on iOS & Android" chip.
• Partners section: generic filler replaced with accurate product copy.
• FAQ rebuilt for the current product (work types, escrow payments, fees + Gibwork Plus, mobile, agents).
• site-config.ts / layout.tsx: added store URLs, replaced stale description (dropped "paid Q&A", which is no longer in the product).

Design notes

• Built entirely on the existing system: shadcn primitives, Tailwind design tokens, FADE_UP_ANIMATION_VARIANTS, lucide icons. No new dependencies.
• Responsive — verified at 1280px and 390px.
• The $WORK token is intentionally left off the page, consistent with its current commented-out state across the repo.

Verification

• npx tsc --noEmit passes
• next build compiles and prerenders /
• git apply --check against a fresh clone passes

Needs maintainer confirmation

• appStoreUrl is a placeholder (apps.apple.com/app/gibwork) — please drop in the exact App Store ID/slug. Play Store URL is verified.
• Mobile section uses an illustrative mockup; happy to swap in real app screenshots if you share them.
