- Added TitleKey and DescriptionKey fields to ToolSpec for dynamic localization.
- Updated tool specifications to use i18nx for titles, descriptions, and appendices.
- Refactored notification messages to utilize i18nx for localization in conversation and ticket assignment events.
- Improved localization in the debug dialog component for skill definitions.
- Added new translation keys in English and Chinese for ticket and conversation assignment notifications.
- Ensured that fallback messages are properly localized based on user locale.
