* fix bug(568): Improve scroll-to-bottom logic

Replaced the "smart scroll" mechanism with a simpler "follow" behavior. The message list now automatically scrolls to the latest message unless the user has scrolled up.

- A new `followIncomingMessages` state tracks whether to auto-scroll.
- Scrolling now uses `scrollToItem` instead of `animateScrollToItem` for immediate updates.
