refactor: enhance auto-focus behavior in Composer component

Browse source 
- Implemented a mechanism to auto-focus the editor immediately after the first message is sent, improving user experience by allowing quick follow-up queries.
- Introduced a reference to track the previous state of the thread to ensure focus only occurs during the transition from empty to non-empty.
