Switch Windows backend DeviceIoControl command paths to a shared per-thread OVERLAPPED event flow, correctly handling immediate completion, ERROR_IO_PENDING, and completion failures on async handles. Add fixture/unit coverage for event usage and pending waits, and update UMDF packaging/docs to run in a dedicated high-priority host process and document the overlapped command behavior.
