- Implemented ChatScrollController to manage scroll behavior and visibility of jump-to-bottom button. - Added functionality to automatically scroll to the bottom when the keyboard opens. - Created JumpToBottomButton widget that appears when the user scrolls up, allowing quick navigation back to the bottom of the chat.
