Xx af6c9f05de feat: Update installation script and improve error handling
- Updated `install.sh` to include versioning and enhanced bilingual messages for better user feedback.
- Refactored platform detection logic to dynamically set binary names based on the version.
- Added checks for system requirements, including curl installation and write permissions.
- Improved error handling with context-specific messages for better debugging.
- Cleaned up the `go.mod` file by consolidating dependency requirements.

This commit enhances the installation process and user experience by providing clearer feedback and ensuring necessary prerequisites are met.
