- Integrated i18n translations for trace logging messages in the Assistant's Stream method, improving localization for user-facing messages. - Updated logging in the OpenAI provider and CUI writer to utilize i18n for error messages, enhancing clarity and consistency across different locales. - Added new embedded template handling in the i18n package, allowing for more flexible message formatting with variable substitutions. - Improved test coverage for i18n functionalities, ensuring robust handling of various translation scenarios and edge cases.
