Scroll to bottom affordance is present for long conversations

In any non-trivial conversation the user will scroll up to re-read earlier answers, copy code, or check context, and without a scroll-to-bottom affordance they miss new streaming responses entirely. Messages arrive silently off-screen and the user assumes the AI is still thinking or has failed. The industry convention established by ChatGPT, Claude, and Gemini is either auto-scroll on new message or a floating jump-to-latest button, and users have learned to expect it.

In your chat component at src/components/chat/ChatWindow.tsx, add a useRef anchor after the last message and a useEffect that scrolls it into view whenever the message count changes. For a polished UX, only auto-scroll when the user is already near the bottom.

const messagesEndRef = useRef<HTMLDivElement>(null);
useEffect(() => {
  messagesEndRef.current?.scrollIntoView({ behavior: 'smooth' });
}, [messages.length]);
