Explicit profile selections from the power panel or menu are now saved
under an ac/battery key in ~/.local/state/omarchy/powerprofiles and
reapplied on boot and on plug/unplug. Only successful, user-made
selections are persisted, so the performance/balanced defaults still
apply when nothing has been chosen.
All entry points key off the same power signal, UPower's OnBattery:
the shell reads it natively and omarchy-powerprofiles-set autodetect
queries it via busctl. This replaces the sysfs online checks, which
disagreed with the shell on desktops without power_supply entries and
lagged behind plug events on some USB-C laptops.
Plug/unplug switching moves from the udev rule into the shell's battery
service, which already receives UPower's debounced state changes, so
the udev rule and its settle-sleep workaround are gone.
