I have never heard of nor seen a case of asymptomatic herpes whitlow. By definition, it is symptomatic. I really don’t think this is something you would be worried about at all! Your hands could have come in contact with asymptomatic shedding, yes, but the skin of the hand is too thick for virus to penetrate without some break in the skin. And if you had a break in the skin and contracted HSV as whitlow, you would have had symptoms.
