Correct a stale count repeated in four places: 10 floating pins, not 23

Recounted at catalog 18a6d2d8: 66 unique pins — 48 full X.Y.Z, 6 two-part
lines, 4 major lines (10 float), 8 exact versions wearing a variant suffix.
The '23' carried since v0.233.0 matches no definition the catalog supports.
Definition written down beside the number so it can be rechecked.

Also: CONTEXT said the fleet floor was 0.257.0; the hub says 0.259.0.

Comment and doc only — no behaviour change.
