The sampler no longer reaches into a sibling pack at runtime: the crop path
planner and its helpers now live here as bfs_crop_planner.py and
bfs_subject_crop.py, copied from drozbay/MaskVidExperiments (d98cc89, v0.2.0).
Both packs are GPL-3.0, which is what makes the copy legal; attribution is in
NOTICE and in each file's header. Only the ComfyUI node classes were dropped
-- they stay in the original pack, where they belong.
tracked/zoomed therefore work out of the box now, and the per-frame paste-back
is ours rather than a call into their uncrop node.
Also adds the node's help page (docs/BFSHeadSwapMaskedSampler.md, the '?' on
the node): what each crop mode does, why the mask is native inpainting rather
than a LoRA feature, why latent_mask is the output to check first, how to size
the latent to the crop, and the order to switch things on when a run looks
wrong. scipy is now a declared dependency (the planner uses ndimage).
