configure catalog — 2.1.172–176 settings added

ork's configure skill keeps a CC-settings catalog (references/cc-version-settings.md). It stopped at 2.1.152/170; this PR adds the 2.1.174–176 settings surface. Click a setting for ork's action.

Bugfix-only releases (2.1.171/173/177) add no settings. The catalog's broader 2.1.153–171 backfill is out of scope here (this PR targets the 2.1.176 adoption head).
