My 3 year old is the whiniest most insufferable human being on earth...

I can't even believe I have to make a whiny post about this just to vent about my whiny child, but here I am. Each day she gets worse and worse, whining about EVERYTHING and crying about utter nonsense, it seems like she can't go 5 minutes without whining and then crying about something anymore and the crying is so insufferable I'm pulling out what little hair I have left. I just don't get it, the other kids in her daycare aren't like this, neither my wife nor I are like this, where did this behavior come from? Over the last 6 months it just seems like she's become this rotten, miserable little animal that doesn't listen to a single thing told to her.

Every single evening the last hour is torture and it doesn't matter if she naps in the afternoon or not these days, tonight it was whine/crying about being told she couldn't spray water onto an electronic telescope, then when offered an alternative (a dry wipe) she throws it at me. Then she has a tantrum meltdown about the dog lying on a blanket on the floor, then she has a tantrum about having to go upstairs to go to bed, whines and cries about needing to sit on the toilet, THEN whines/has a meltdown about having to get off the toilet, then has a ridiculous meltdown about having to wash her hands AND dry them with a hand towel. Finally get her in her room, has a meltdown about having to put her pajamas on arms first.

And her whine cries are so obvious now, a very specific pitch/tone and you know that in 60 seconds she's going to be distracted with something else and the whining/crying will cease immediately. Absolutely nothing has worked, not redirecting, not reasoning, not pleading/bargaining, not bribing, not explaining, not forewarning, not challenging, not yelling, nothing. I'm at my wits end, about 10 minutes away from yeeting this monster right out of the house and having some peace and quiet.

EDIT: whew, woke up to far more responses then I expected, I will try to get through some of them today. Hopefully the responses I've already posted to comments last night answer/reflect where we're at. Thanks for all the suggestions!
