chore: drop the stale planned-operations closure approval (#2373)

The APPROVED_OVER_CEILING row for packages/command-registry/src/planned-operations.ts
was consumed by #2329. Now that main carries the entry, the no-growth rule governs it
and the row can no longer change any verdict, so the "no row is stale" probe fails on
main and on every PR based on it. Remove the row, as the probe instructs.
