Replace broken Twitter embed with direct link widget

Twitter/X changes make live feed embedding impossible without cost:
- Official embed widget broken/deprecated
- Twitter API requires $100/month minimum for timeline reading
- Nitter instances unreliable and shutting down
- No free alternatives that don't require subscriptions

Solution: Clean, professional widget that links directly to X timeline
- Shows X logo and @openworm handle
- Clear call-to-action button to view timeline
- Zero dependencies, zero cost, never breaks
- Replaces broken Twitter widgets.js integration
