Fix action triggering by using kitten output instead of remote control

The RC approach sent actions targeting the overlay window itself rather
than the underlying window. Switch to the standard kitten output pattern:
the Go kitten outputs the selected action definition via
KittenOutputSerializer, and handle_result in Python calls boss.combine()
with the correct target window after the overlay closes.
