Add iOS share extension with rich link previews

- Implement share extension to receive URLs from other apps
- Display shared links with emoji indicator and rich preview cards
- Add custom compact link preview with image, title, and domain
- Configure app groups for data sharing between extension and main app
- Handle URL detection and parsing in share extension
- Update message formatting to show only emoji for shared links
- Add proper entitlements and activation rules for share extension
