πŸ’‘ What: Added an automatic downward scroll when new messages are added to the chat timeline, and applied standard ARIA live region attributes (role="log", aria-live="polite", :aria-busy="isSending") to the chat container.

🎯 Why: To solve two critical UX/accessibility issues in the Console view:

  1. Users previously had to manually scroll down to read the latest responses, which interrupts the conversational flow.
  2. Screen reader users were entirely blind to dynamically appended messages or the 'sending' loading state, making the chat interface inaccessible.

πŸ“Έ Before/After: Visuals verified locally via Vite preview and Playwright screenshots. The view now smoothly auto-scrolls to the bottom upon new messages.

β™Ώ Accessibility: Added explicit live regions so assistive technologies announce new log entries and loading states.
