fix(quant): load offline-quantized compressed-tensors checkpoints directly on CPU under offload
...
The diffusion loader treated any quant config without the MXFP8/
is_checkpoint_quantized markers as online quantization: it loaded every
component on the accelerator before offloading, so serving the int8
weight-only compressed-tensors artifact OOM'd at model construction
(encoder 17 GiB + VAE + packed DiT skeleton > 24 GiB). compressed-tensors
is always a serialized format with no on-load quantization pass — detect
it (through component wrappers too) and load on the host, round-tripping
each quantized module through the accelerator only for the post-load
Marlin repack, which has no CPU path.
