Option to add extra args to providers

option to add extra args to prompt.

In my case i don't want a session per code change in clause so i add "--no-session-persistence"

vim.iter is only available For Neovim 0.10+. don't know what version comp you looking for

master has changed a lot and i want to think about this still. I love the idea of passing additional params, but part of me thinks this should be on the opts passed into the function as opposed to on the state object.

i could go either way, but for now, let me think on it for a while.

also everything has been severely refactored. i am ~75% way through a great refactor and i will continue to refactor until my own morale improves :)

The big thing for me was making a more consistent and sensible interface to manage lifecycles of data.

now things are mostly good
