We've had consistent failures recently of free-threaded python with async and sharded/replica clusters on win32 variants: https://spruce.corp.mongodb.com/task/mongo_python_driver_test_win32_test_standard_v7.0_python3.14t_async_noauth_ssl_replica_set_1cbb9ae6e742502366ba5fa059b93389e54f310f_26_08_27_18_03_57/logs?execution=0 and https://spruce.corp.mongodb.com/task/mongo_python_driver_test_win32_test_standard_v9.0_python3.14t_async_auth_ssl_sharded_cluster_1cbb9ae6e742502366ba5fa059b93389e54f310f_26_08_27_18_03_57/logs?execution=0.

This is due to literally exhausting the memory available to the 32-bit process. We already exclude PyPy from win32 and should do the same for free-threading.
