KoolbaseAuthGate, KoolbaseAuthScope, KoolbaseCollectionList, and
KoolbaseCollectionController ship as the first behavioral widgets: the
SDK now encodes auth branching and the stale-while-revalidate list
contract as composable components rather than patterns every app
hand-writes. Query refresh streams are now keyed by query identity
rather than collection name, matching their documented contract — see
the changelog behavior note. README gains a Widgets section and catches
up two versions of version-string drift (was still ^10.1.2).
