RFD3 error with inference_sampler.allow_realignment option

I'm getting this error in RFdiffusion3 when running motif scaffolding with allow_realignment=True

RuntimeError: "svd_cuda_gesvdjBatched" not implemented for 'BFloat16'

I'm wondering if this is a bug or a mistake in my command

rfd3 design \
        out_dir=test \
        inputs=input.json \
        dump_trajectories=True \
        prevalidate_inputs=True \
        inference_sampler.allow_realignment=True \
        n_batches=1 \
        diffusion_batch_size=1

with this example json file used as input:

 {
     "test": {
         "input": "7v11.pdb",
         "ligand": "OQO",
         "unindex": "A431,A572-573",
         "length": "200",
         "select_fixed_atoms": {
             "A431": "TIP",
             "A572": "BKBN",
            "A573": "BKBN"
        }
    }
}

The error does not occur when doing unconditional generation with allow_realignment=True set or when doing motif scaffolding without the argument.

Start at foundry/utils/alignment.py:60 and reproduce the provided rfd3 command with the example input. Compare the dtype paths for motif scaffolding with allow_realignment=True against unconditional generation and motif scaffolding without the option. Done means the reported BFloat16 SVD error no longer occurs for the supplied motif-scaffolding case.
