The update conflict tests stub sudo and pacman, but omarchy-update-pacman now puts systemd-run between them, so on a systemd-booted host the tests would reach for the real system manager. Stub systemd-run to drop the wrapper's options and run the command, and cover the helper's own invocation composition in a new test. Raised by codex review.
