We should be able to remove these deps from shuttle-runtime too, which should be a nice compile time win for users.

Oh, and the tests here need to be updated.

Done. I actually removed the custom tracing layer injection. We'll have to follow up with a subscriber here if we want to structure the pre-user code logs or filter them. We'll probably want to set up some filtering within the business logic of the codegen, but still TBD.

Do we want to add back a macro annotation for enabling a default tracing subscriber like the one we've been using thus far?

I wouldn't for this PR. We will track though this discussion separately in a ticket.
