Late-bound merge-on-arrival hook. GlobbableApi registers a
function at module load that handles the "moved Globbable arrived
in a container holding a mergeable sibling" ripple. Lives here as
a slot rather than a direct import to avoid the
containment → glob → containment cycle.
The hook fires AFTER post-move on* witnesses so subscribers see
the arrival before the absorbed Stuff destructs. Hook implementor
is responsible for the MixinApi.isGlobbable skip path.
