William Gill 2cecf77981 Pin transformers <5 — comfyui_segment_anything's GroundingDINO needs it ...

transformers 5.0 removed BertModel.get_head_mask (it was on the legacy
4.x API). comfyui_segment_anything's GroundingDINO bertwarper.py still
calls bert_model.get_head_mask in __init__, so first inpaint crashes
with AttributeError. Pinned transformers>=4.40,<5 in two places:

  - Dockerfile: applied AFTER the custom node's requirements.txt
    install so it wins on a fresh image build.
  - install-custom-node-deps.sh entrypoint: re-applied at every
    container start so any future custom-node install (via
    ComfyUI-Manager or volume clone) that pulls a newer transformers
    transitively gets pinned back into the working range.
