A box drawn around a part of the graph is part of it, so a fit frames it and a band catches it (#95)

Fit measured the nodes alone: a group drawn around them was cut off, and a graph holding nothing
but a comment framed the empty origin. It now frames both sorts together.

The rubber band ignored boxes entirely. It catches them now, into the *same* selection as the
nodes — `nodeIds` and `annotationIds` side by side — so one drag moves all of it, one Delete
removes all of it, and one undo takes it back. A box counts only when the band holds all of it,
where a node counts on touching: a group wraps the nodes it holds and therefore overlaps every
band drawn over any of them, and since it drags those nodes along, catching it by accident would
be felt at once.

A node inside a selected group is moved once, not twice — `travellers()` collects everything one
gesture carries and lets each thing appear in it a single time.
