fix: Stop Rust highlighting path as local See attached issue. I don't love the solution, but am not sure how else to attack the problem. We want to match almost every `identifier` in the scope. We don't want to match scoped identifiers, so the best I could come up with (without restating large chunks of `highlights.scm`) was to repeat the negative case. I think this could be another use case for `#has-ancestor?`, (or `#not-has-ancestor?` technically), but unless that gets added, I think this is the most straightforward solution.
