[utility] useHookParams

[florian-lefebvre]

I wonder if can add a bit of magic using https://github.com/unjs/unctx, basically a wrapper that puts all those arguments in a context so that inside a utility we can just call

const { command } = useHookParams("astro:config:setup")

and that would even allow us to automatically expose args from previous hooks instead of having a let config: AstroConfig inside the function body
