v0.1.3

v0.1.3 — Texture pipeline upgrade

Inspired by sosadly-quality texturing (not a kitchen-sink brush dump):

• pack_box_uv — shelf-pack box UVs so faces do not share pixels
• shade_model_base — region colors + soft face lighting + mottle + blur
• paint_face_features — batch face-local ops (fill/rect/ellipse/line)
• get_texture — inspect the sheet as compact PNG
• scaffold_biped now packs UVs automatically
