Bernardo Magri 51c11e1df3 feat(idle): suspend on battery only, cohering with power management
hypridle's suspend listener now runs `nomarchy-on-ac || systemctl
suspend`, so a plugged-in machine no longer suspends itself mid-idle
(long builds, media, presentations survive). It also fires sooner —
15 min, vs the old fixed 30 — since it now only applies unplugged.
Lock and screen-off are unchanged on both power sources, and logind's
lid handling stays at its sensible defaults (suspend on lid close,
ignore when docked).

Closes the idle-cohesion follow-up under the laptop-power roadmap item.
