mesh/merge-gate pass: builds dunst, messenger → g14, novox, shanks; no bus step; every machine composes with the change as it did without (4 of 4 compose)
The operator could not tell from a notification whether to act, nor act without
opening a session. Each message now opens with a verdict, a warning that needs
nothing is not sent, and a notification offers answers the messenger performs
through their seat verbs; dunst's send gains actions and says the chosen one
(hq ADR 0253).
Owns one dunstrc (the laptop's, in the interface face, its menu on the seat's
dmenu command) and the dunstrc.d directory for other modules' rules; D-Bus
starts it, so nothing else does. Go tools over the session bus.
