feat: improve text output with article preview, quote tweets, and media

Enhance the text output format to show more useful information:

- Article tweets: Show 📰 indicator with title + preview text in feeds,
  full body when reading single tweets
- Quote tweets: Display quoted content with ┌─ QT @user formatting
- Media: Show 🖼️/🎬/🔄 indicators with URLs for photos/videos/GIFs

Also refactors single tweet read to use shared printTweets function
for consistent formatting.
