This adds a `hasAnyBinding` helper that checks whether an identifier has any scope binding at all (regardless of what it's bound to). The unbound-fs fallback now only applies when there is truly no binding in scope, preventing false positives for non-core fs bindings. Also restores the `const fs = require("mock-fs"); fs.mkdirSync(...)` valid test case that was incorrectly removed in the previous commit.
