Replace logging macros with std::cout for help text output

- Replace LOG_INFO macros in help text with std::cout statements
- Replace LOG_ERROR macros for help-related error messages with std::cout
- Add #include <iostream> for std::cout support
- Ensures help text is printed directly to stdout without going through logging system
