Bit-identical copy through a FRESH primitive node (mx.copy). Unlike
contiguous, this always creates a new graph node even for an already-
contiguous input — the tool for DETACHING an array from a multi-output
primitive's sibling set (a retained sibling output pins every co-output's
buffer natively; see gatedDeltaUpdate's state detach, 2026-08-20).
