plots: dejargon, drop redundant titles, emit png+svg+pdf, CSV re-render

Audit of all 4 plot scripts (plot_dynamics/substrate/emergence/deploy_overlay):
- One save_fig(fig, path) helper in figs.py writes png+svg+pdf (vector for the
  paper, png for the blog). All scripts call it.
- arm_label() map: reader-facing names only -- route2->route, drop 'knob'/'the
  cheat' from titles and the train-vs-deploy story (adapter on/off, reward hack).
- Titles off by default (the paper/blog caption carries it); --title re-enables
  for standalone research use.
- dump_data CSV now carries every plotted series; plot_dynamics --from-csv
  re-renders the three figures from the committed CSV with no logs (logs/ and
  out/runs/ are gitignored; out/figs/*.csv is tracked). Round-trip verified.
- Commit the regenerated dyn_sub4 figures in all 3 formats + the CSV.
