Call post_init in HfMoondream2da5c05d

This updates hf_moondream.py to call self.post_init() after constructing HfMoondream.

Why:

  • Newer Transformers v5 load paths expect PreTrainedModel.post_init() bookkeeping to have run.
  • Without this, loading moondream/moondream3-preview can fail with AttributeError: 'HfMoondream' object has no attribute 'all_tied_weights_keys'.

Validation:

  • Reproduced the v5 load failure before the change on a remote H100.
  • Verified successful GPU load + query after the change with transformers==5.3.0.
  • Verified successful GPU load + query after the change with transformers==4.51.1.
