MarinFold exp75 checkpoints

Final checkpoints from the MarinFold contacts-v1 1.5B tuning sweep tracked in Open-Athena/MarinFold#75.

Both checkpoint formats are retained:

• hf/ contains a Qwen3ForCausalLM Hugging Face safetensors export with the contacts-v1 tokenizer colocated with the weights.
• checkpoints/ contains the original Levanter OCDBT checkpoint for training restart or re-export.
