Fix keyUp when command is down

[Kingminer7]

Basically theres an issue where keyUp isn't called if command is down - this fixes that.

Only tested on intel, testing needed on m1

side note: not sure if this is 100% the way I should be hooking objc, lmk if its not

tried to but couldn't get it to stop crashing on startup, seems to be whenever the function for the hook runs
