…ks which access refs, but ban hooks from taking direct ref value arguments"

Summary:
This brings the behavior of ref mutation within hook callbacks into alignment with the behavior of global mutations--that is, we allow all hooks to take callbacks that may mutate a ref. This is potentially unsafe if the hook eagerly calls its callback, but the alternative is excessively limiting (and inconsistent with other enforcement).

This also bans *directly* passing a ref.current value to a hook, which was previously allowed.
