feat: add automated cross-platform install script for CodeGPT CLI (#237)

- Add a shell script for installing the CodeGPT CLI with automatic OS and architecture detection
- Download and install the appropriate CodeGPT binary and set executable permissions
- Append the CodeGPT installation directory to PATH in the user's shell config file based on detected shell
- Include error handling for unsupported platforms or architectures and for missing shell config files
- Provide colored terminal output and informative error and status messages
