>This isn’t merely semantically incorrect because it suggests the use of time travel, it’s grammatically incorrect because the verb is just conjugated incorrectly for the tense of the sentence.

No, it's not. The point in "will run yesterday" and "sleep furiously" is actually exactly the same: Grammatically correct, semantically nonsensical. The effect of "yesterday" really isn't any different from "furiously" here, as it does not influence the grammatical tense. They are just adverbs that add meaning that is nonsensical. They're just sitting there in their correct grammatical positions. There really is nothing wrong with the conjugation of the verbs - It would be wrong it if it was "will ran", for example.
