Description#

Plain factory for the reorder-commit flow used by CngxReorderableMultiSelect. Operates on ordered arrays with same-membership semantics.

Why a separate factory (not a flag on createArrayCommitHandler): the array handler's reconcileValues uses sameArrayContents to short-circuit writes when the target matches current state - a pure reorder would silently skip. A bypassReconcile flag would complicate every other call-site; a dedicated factory keeps the array handler's hot path small.

CngxTreeSelect.dispatchValueChange follows the same pattern inline; a future refactor could lift it here.
