docs: R-168 is CLOSED — correct the stale "CI is still owed" sentence carried into the trim (R-229)

Found by the checklist's own last item (confirm your push's CI run by run ID). Corrected here and
in the three sibling repos. Ledger J2 records the two lessons: a trim is a VOLUME operation and
carries stale claims forward unless each is re-checked, and the gate cannot catch this class --
"this register item is closed" is not mechanically checkable from the instruction file.

 **The pre-push hook** (`.githooks/pre-push`) runs it with `--fast` and refuses a failing push. It is
