/**
 * Returns a patch whose vectors are plain copies.
 *
 * The engine reports transforms as live references into objects it keeps reusing
 * — `DIVENode.onMove` hands out a scratch `Vector3` that the next frame
 * overwrites. Storing such a reference means the stored schema silently changes
 * underneath its owner, and `lodash.merge` assigns by reference whenever the
 * target key is absent.
 *
 * This used to be `copyVec` at each call site in the gateway. It lives here
 * because `EntityRegistry.write` is now the only way into a schema, so copying
 * can happen once instead of being remembered every time.
 *
 * @param patch - The patch to sanitise.
