When a new external session was detected, the session list entry would
appear completely blank/black until clicked or page reloaded. This was
caused by a race condition between React's render cycle and the
useEffect that marks sessions as "new":
1. Session added to state, component renders with isNew=false
2. motion.div mounts with initial={{ opacity: 0 }}
3. Animation to opacity: 1 fails to trigger properly
4. useEffect runs, sets isNew=true, but initial only applies at mount
The fix:
- Only apply opacity: 0 initial state when item is confirmed as new
- Disable layout animations for new items to prevent conflicts
Items now appear immediately on first render, and the entry animation
plays correctly once the useEffect confirms them as new.
