add support for triggering with zsh zle

[zzh8829]

something similar to this

https://github.com/loiccoyle/zsh-github-copilot

so i can type the command first and then trigger ai after half of the command has already been typed.

Does it have to be after you type the command, or can it be before? For example, you hit CMD + i, and then type the command. Or would you rather type the command, and then hit CMD + i to run uwu?

I try to get this working for like an hour last weekend and could not figure it out. Might be something borked on my machine, or conflicts with Power Level 10k.

I want this too, will take another crack at it when I have time.
