feat(settings): deny-list hardening pass (audit #20)

- rm -r / rm -fr denied (only -rf was; flag-order variants passed).
- python3 -c / python -c ask → deny: aligned with node -e / perl -e /
  ruby -e (arbitrary-interpreter class was incoherently split).
- git push <remote> +<ref> denied (refspec force carried no flag).
- --force-with-lease un-over-blocked: --force* split into --force /
  --force *, so the safer variant now falls to the git push ASK gate.
Deny 99 → 105, ask 19 → 18. Second curtain unchanged (auto-mode
classifier, BDR-004). doctor's deny sentinel tracks HEAD (LOT 1).
