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.

Consolidate the WirePlumber camera priority file under the same
host_i3_dotfiles mechanism used for autorandr, dropping the bespoke
copy task from profile_desktop_host/tasks/nymph.yml.

Delete all Arch-specific files (packages_arch role, profile_desktop_gnome
role, arch.yml group_vars, nymph.yml host_vars, arch dotfiles). Revert
nymph to the void group in inventory, remove the arch play from site.yml,
and restore profile_desktop_host/tasks/nymph.yml to its pre-Arch state
(GRUB + NVIDIA + prime-run). Preserve Void improvements introduced
alongside Arch work (desktop_void_dotfiles, desktop_void_source_tools,
profile_desktop_i3 dir additions, void-specific conditions).
