feat: Enhance installation script with improved configuration and error handling

- Updated `install.sh` to allow customizable download directory and binary retention options.
- Added argument parsing for `--keep-binary` and `--download-dir` to enhance user flexibility.
- Improved binary verification process with clearer error messages and executable permission settings.
- Streamlined download process by directly saving to the specified download path.
- Enhanced user feedback with instructions for making the downloaded file executable.

These changes improve the installation experience by providing users with more control and clearer guidance during the setup process.
