Offline running failing due to HunyuanVideoTransformer3DModelPacked

Nobody has claimed this yet.

The app is running perfectly fine when internet available

All models downloaded into

`os.environ['HF_HOME'] = os.path.abspath(os.path.realpath(os.path.join(os.path.dirname(__file__), './hf_download')))`

When i set like below

```
# Set local_files_only based on offline mode
local_files_only = args.offline
if local_files_only:
print("Running in OFFLINE mode - using local models only")
# Disable any online connections for HuggingFace when in offline mode
os.environ['HF_HUB_OFFLINE'] = '1'
os.environ['TRANSFORMERS_OFFLINE'] = '1'
os.environ['DIFFUSERS_OFFLINE'] = '1'

# Load models with local_files_only parameter when in offline mode
text_encoder = LlamaModel.from_pretrained("hunyuanvideo-community/HunyuanVideo", subfolder='text_encoder', torch_dtype=torch.float16, local_files_only=local_files_only).cpu()
text_encoder_2 = CLIPTextModel.from_pretrained("hunyuanvideo-community/HunyuanVideo", subfolder='text_encoder_2', torch_dtype=torch.float16, local_files_only=local_files_only).cpu()
tokenizer = LlamaTokenizerFast.from_pretrained("hunyuanvideo-community/HunyuanVideo", subfolder='tokenizer', local_files_only=local_files_only)
tokenizer_2 = CLIPTokenizer.from_pretrained("hunyuanvideo-community/HunyuanVideo", subfolder='tokenizer_2', local_files_only=local_files_only)
vae = AutoencoderKLHunyuanVideo.from_pretrained("hunyuanvideo-community/HunyuanVideo", subfolder='vae', torch_dtype=torch.float16, local_files_only=local_files_only).cpu()

feature_extractor = SiglipImageProcessor.from_pretrained("lllyasviel/flux_redux_bfl", subfolder='feature_extractor', local_files_only=local_files_only)
image_encoder = SiglipVisionModel.from_pretrained("lllyasviel/flux_redux_bfl", subfolder='image_encoder', torch_dtype=torch.float16, local_files_only=local_files_only).cpu()

transformer = HunyuanVideoTransformer3DModelPacked.from_pretrained('lllyasviel/FramePackI2V_HY', torch_dtype=torch.bfloat16, local_files_only=local_files_only).cpu()

```

and run with turning off internet i get below error

`local_files_only = set as True`

Start at app.py line 72 and inspect the HunyuanVideoTransformer3DModelPacked.from_pretrained call and its offline-loading path. Reproduce with the offline flag and local model files; done means the transformer loads without attempting to contact huggingface.co when internet access is unavailable.
