fix: Correct binary verification message and improve download error handling in install.sh

- Fixed a character encoding issue in the binary verification message to ensure proper display.
- Updated the curl command to use a progress bar instead of verbose output, enhancing user experience during downloads.
- Improved the error message for failed binary downloads to include HTTP status information for better debugging.

These changes enhance the reliability and clarity of the installation script, providing users with more accurate feedback during the installation process.
