-The warning was triggered by using decltype(&PCLOSE) to deduce the deleter type for the std::unique_ptr member m_pipe. While decltype(&PCLOSE) correctly deduces the function pointer type, the compiler flags this as a potential issue because attributes associated with the function pointer type (if any existed in the definition of PCLOSE) are ignored when used as a template argument.
To resolve this warning, the deleter type for std::unique_ptr is now explicitly specified as int (*)(FILE*). This directly states the function pointer type expected for PCLOSE and avoids the attribute deduction issue.

This is a code quality improvement and does not change the functionality of the CommandExecutor class. It only modifies the type declaration of the m_pipe member.
