Choosing an Effect > Pathfinder item (Add, Intersect, Exclude, Subtract...)
with several loose objects selected now groups them and applies the live
effect to the group, in one undo step, so the result shows at once and stays
editable. A selection that already holds a group, or a single object, works
as before, and agents get `grouped: true` back when it happens.
Root cause: Pathfinder effects combine the contents of a group or layer.
Applied to loose objects, each one got an effect with nothing to combine, so
nothing visibly changed, while the Pathfinder panel's commands (found by the
command search) act on the selection directly.
