Enhance GitHub Actions workflow for cross-platform executable testing

- Added separate steps for testing executable functionality on Windows, macOS, and Linux, improving clarity and organization.
- Streamlined the executable path determination for Windows and implemented similar logic for macOS and Linux.
- Enhanced error handling and output messages for better debugging during the testing process.
