Description
Follow-up from #89 (Scoped credentials for outgoing HTTP).
Existing tests cover some leakage paths: resolver_failure_surfaces_as_error asserts the failure diagnostic does not leak, and isolated_registries_across_sandboxes proves cross-sandbox isolation.
However, there is no positive test that runs a guest with a known sentinel token value and scans stdout / stderr / every error payload to assert the sentinel string is absent from every guest-visible output. Add such a canary sweep test.

Research direction
Locate the existing resolver_failure_surfaces_as_error and isolated_registries_across_sandboxes tests, then trace the scoped-credentials guest setup from #89. Add a guest test using a sentinel token that scans stdout, stderr, and every error payload; done means the sentinel is absent from all guest-visible outputs.
