Previously the task hardcoded GRUB_CMDLINE_LINUX to a fixed string containing nymph's rd.luks.uuid, rootflags and apparmor parameters, clobbering whatever the host had. Switch to an idempotent lineinfile-with-backrefs loop that appends nouveau.modeset=0 and nvidia-drm.modeset=1 only when missing, preserving the existing kernel cmdline. grub-mkconfig now runs only when the cmdline changed.
