Since it didn't get worse and she's not acting uncomfortable, I'm taking the advice I've gotten here and not worrying but will mention it to the vet the next time she's there. (Overdue for a checkup and shots, come to think of it.)
I had another thought occur to me ... given that a) she doesn't seem to breathe through her mouth when suffering nasal congestion, but continues to force air through her nose, and b) her head and her lungs are so close together due to being cat-sized, I wonder whether the creaky sound that I thought was coming from her lungs was actually being generated in her nose and conducted through her body...?
