Clears the once-per-process claim on the affinity-clamp warning. Test-only.
The warning is said once per process by design, which makes it a single-shot observable: a test that provokes it consumes it for every test after it in the same process. Resetting is what lets a negative control ("this configuration says nothing") run after a positive one and still mean something.
