This is unrelated to the changes in this PR, but since we are doing the same thing for the commit.Action field in the next commit, it makes sense to do it for Status too for consistency. Modelling this as an enum feels more natural than modelling it as a string, since there's a finite set of possible values. And it saves a little bit of memory (not very much, since none of the strings were heap-allocated, but still).
