chore(plugin): mint 2026.09.19.1614 for the using-scribe force-axis edit

The five-answer change touched plugin/skills/using-scribe/SKILL.md, and CI
7052 caught the manifest still reading 2026.09.18.1606. Per #2209 the
marketplace clone self-updates but the cache that actually executes only
refreshes on a version change, so without this the new guidance reaches the
repo and stops there.
