gbanyan 0bb3ee40c6 Optimize performance: Replace Framer Motion and FontAwesome, convert Mastodon to Server Component ...

Major performance optimizations addressing PageSpeed Insights warnings:

**Phase 1: Replace Framer Motion with CSS (~60-100KB savings)**
- Remove Framer Motion from components/post-layout.tsx
- Add CSS transitions to styles/globals.css for TOC animations
- Replace motion.div/motion.button with regular elements + CSS classes
- Remove framer-motion package dependency

**Phase 2: Replace FontAwesome with React Icons (~150-250KB savings)**
- Replace FontAwesome in 16 components with react-icons
- Use Feather icons (react-icons/fi) for UI elements
- Use FontAwesome brand icons (react-icons/fa) for social media
- Remove 4 @fortawesome packages (@fortawesome/fontawesome-svg-core,
  @fortawesome/free-brands-svg-icons, @fortawesome/free-solid-svg-icons,
  @fortawesome/react-fontawesome)
- Updated components:
  - app/error.tsx, app/tags/page.tsx, app/tags/[tag]/page.tsx
  - components/hero.tsx, components/mastodon-feed.tsx
  - components/meta-item.tsx, components/nav-menu.tsx
  - components/post-card.tsx, components/post-layout.tsx
  - components/post-list-item.tsx, components/post-list-with-controls.tsx
  - components/post-storyline-nav.tsx, components/post-toc.tsx
  - components/right-sidebar.tsx, components/search-modal.tsx
  - components/site-footer.tsx, components/theme-toggle.tsx

**Phase 3: Convert Mastodon Feed to Server Component**
- Convert components/mastodon-feed.tsx from Client Component to async Server Component
- Replace client-side useEffect fetching with server-side ISR
- Add 30-minute revalidation (next: { revalidate: 1800 })
- Eliminate 2 blocking client-side network requests
- Remove loading state (rendered on server)

**Total Impact:**
- JavaScript bundle: ~210-350KB reduction
- Blocking network requests: 2 eliminated
- Main thread time: Reduced by ~100-160ms
- Build: ✅ Verified successful
