    Function: ensureDirectoryExists
    Description: Creates all missing directories present in the given file path.
                Iteratively parses the path and creates each directory level
                using _mkdir() before file operations are performed.
    Parameters:
        - filePath: const std::string&, relative or absolute file path
    Returns:
        - void
    Throws:
        - None (_mkdir failures are intentionally ignored if directory already exists)
