feat(i18n): Enhance internationalization support and error handling messages

- Added i18n keys for various error and info messages related to task management, user handling, and storage operations.
- Updated error messages in the watch and task handling commands to use i18n for better localization.
- Refactored error handling in the database initialization and user synchronization processes to provide clearer messages.
- Improved logging messages for better clarity and consistency across the application.
- Added comprehensive documentation for AI collaboration and project structure in the repository.
