Run the process-global queue probe in a subprocess and explicitly drain its synthetic callbacks so parallel free-threaded tests cannot contaminate one another.

Pass the finalization timeout into the child so process isolation does not depend on importing test helpers from the temporary working directory.

Summary
Isolate the CPython pending-call saturation probe so its process-global queue cannot contaminate other tests running concurrently under free-threaded Python. Explicitly drain the synthetic no-op callbacks before exercising cuda.core's existing retry path.
