chore(mako): handfix keepers — clip-curl pose recipe, repair masks, fin_locate

pose_clipcurl_idle.json is the recipe for extracting a clip's pinned curl;
the .txt files are the crosshand-repair vertex masks. The 230 MB of A/B bake
GLBs and render dirs stay out as regenerable scratch (now gitignored);
review/ evidence PNGs were already in the ignored tier.
