        Calculate the next repeat time based on repeat days and target time.

        This function calculates the next execution time for a repeatable task.
        If the current day is in repeat_days and the target time has not passed,
        it returns today's target time. Otherwise, it finds the next matching day.

            repeat_days (list): List of weekdays to repeat (0=Monday, 6=Sunday).
            hour (int): Target hour (0-23).
            minute (int): Target minute (0-59).
            second (int): Target second (0-59).

        Returns:
            datetime: The next repeat execution time.
