feat: add background daemon (#2006)

* init daemon crate

* wip

* minimal functioning daemon, needs cleanup for sure

* better errors

* add signal cleanup

* logging

* things

* add sync worker

* move daemon crate

* 30s -> 5mins

* make clippy happy

* fix stuff maybe?

* fmt

* trim packages

* rate limit fix

* more protoc huh

* this makes no sense, why linux why

* can it install literally just curl

* windows in ci is slow, and all the newer things will not work there. disable the daemon feature and it will build

* add daemon feature

* maybe this

* ok wut where is protoc

* try setting protoc

* hm

* try copying protoc

* remove optional

* add cross config

* idk nix

* does nix want this?

* some random pkg I found does this

* uh oh

* hack, be gone!

* update contributing
