Add chat update functionality and enhance API endpoints in Neo API

- Introduced a new endpoint for updating chat details, allowing users to modify chat titles via the handleChatUpdate method.
- Implemented error handling for missing session IDs and chat IDs, ensuring robust validation of input parameters.
- Enhanced existing API structure by adding status, chat list, chat detail, history, file upload, download, and mentions endpoints, improving overall API usability.
- Improved code organization and maintainability by clearly defining new methods for handling chat updates and related functionalities.
