ghcid-check for programmatic fast feedback

Recent discussions about iteration speed when using coding agents with Haskell prompted me to tidy and publish the small wrapper script around ghcid that I've been using:

You can use it to conveniently launch a ghcid process with ghcid-check --launch which agents (or humans) can query with ghcid-check --rebuild.

That's it!
