Add draw_tire_cuts_png (and a --tire-png flag): one panel per recognised tread showing the annular cycle, up/down/bite teeth, walk-depth labels, and cut slits, ported from medial_tire_cut_labelling.to_tikz. Render the function-D (seed 7) graph's tire cuts. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
