docs(D.2b): IsCarriedBy — note WielderId is wire-only; optimistic wields detected via ContainerId

Code-review minor: prevents a future WielderId-only 'is this wielded?' check
from silently missing an optimistically-wielded item (WielderId==0 until the
server confirm; ContainerId==wielder is the live signal).
