jgrusewski d98ec8d343 fix: pinned host memory for async DtoH readback ...

cuMemcpyDtoHAsync with non-pinned host pointers blocks the CPU on
CUDA 13 / H100 driver 580+ until ALL pending GPU work completes.
With graph_forward + aux_ops + adam queued, this caused multi-minute
hangs between training steps.

Fix: allocate 12 bytes of pinned (page-locked) host memory via
cuMemHostAlloc(DEVICEMAP) for the 3 scalar readbacks (loss, mse_loss,
grad_norm). Pinned memory enables true async DtoH — CPU returns
immediately, GPU copies when it reaches that point in the stream.
