- Introduced a new `is_fallback` property to track when responses are generated without knowledge base matches. - Updated the chat components to display fallback hints and indicators in the UI, enhancing user awareness of fallback responses. - Added translations for fallback hints in multiple languages, improving accessibility for diverse users. - Modified backend logic to emit fallback status in response events, ensuring consistent handling across the application. These changes improve the user experience by providing clear feedback on fallback responses, enhancing the overall interaction with the chat system.
