Modernization release. Summary:

  • current PyTorch/transformers support, no Lightning; safetensors weights, AntiBERTy from the Hugging Face Hub
  • Biopython PDB/mmCIF writer, input validation, alignment-based templates, ANARCII renumbering
  • batched prediction, pooled embeddings, device selection, igfold CLI
  • refinement-loss and geometry fixes (benchmark unchanged within noise; see release notes)
  • pixi environments, tests, pre-commit, CI, PyPI publishing, new Colab notebook

- Support current PyTorch (>= 2.0, safe loading) and transformers (>= 4.36 including 5.x);
  drop the PyTorch-Lightning dependency; model is a plain nn.Module
- Weights in safetensors format with the architecture config in file metadata; converter for
  legacy .ckpt files; IGFOLD_WEIGHTS_DIR override; AntiBERTy weights come from the Hugging Face Hub
- Structures written with Biopython (PDB or mmCIF by extension); per-chain residue numbering
- Input validation with clear errors; optional dependencies raise MissingDependencyError
- Templates aligned to input sequences (mutations and missing residues tolerated)
- Renumbering and Fv truncation with ANARCII (pip-installable) instead of AbNumber
- Batched prediction (fold_batch/predict), pooled sequence embeddings, explicit device selection
- igfold command-line interface (fold, convert-weights)
- Fixes: chain-boundary masks in refinement losses, coordinates from the final refined frames,
  terminal O placement, OpenMM >= 8 units, padded-batch attention masking
- pixi environments (PyPI dependencies, conda for Python only), tests with golden structures,
  pre-commit, CI on Linux and macOS, PyPI trusted-publishing workflow; rewritten Colab notebook
