- Auto-scroll only when user at bottom or just sent; Latest button when scrolled up
- Add unit tests for scroll helper and hook
- Bump version 1.3.5 -> 1.3.6

- Use virtualizer.scrollToIndex for Latest button and initial load so scroll
  works with @tanstack/react-virtual (scrollIntoView was ineffective)

- Simplify MessageList with useCallback for scrollToBottom
- Add unit tests for MessageList ref and scrollToBottom
