Subject: [PATCH] Improve text input behavior: append recognition results to
 text field

- Change from replacing current text to appending final results
- Distinguish between real-time results (display only) and final results (append to text)
- Add proper spacing between appended text segments
- Maintain history of individual recognition segments
- Clear current text when starting new recording session
