Subject: [PATCH] feat(floating-button): add Mevx-style floating quick action
 button

- Create floating-button.tsx content script with inline UI
- Button appears on crypto pages (DexScreener, Twitter, CoinGecko, etc.)
- Shows quick token analysis popup on click
- Displays token price, 24h change, and quick stats
- 'Full Analysis' button opens sidepanel for detailed view
- Update background/index.ts to handle OPEN_SIDEPANEL message
- Gradient purple button with smooth animations
- Fixed positioning (bottom-right corner)
- Clean, modern popup design with inline styles

Implements Task 3: Create Floating Quick Action Button
Similar to Mevx's approach for quick token insights
