Replace the slurp/set_fact Jinja-heavy approach (which was clobbering
pre-existing GRUB_CMDLINE_LINUX content) with a straightforward
sequence: grep to detect whether the line exists, lineinfile to
initialize an empty one when missing, then two replace tasks using a
tempered-greedy-token regex that appends each NVIDIA parameter only
when not already present. Idempotent and preserves any existing
content in GRUB_CMDLINE_LINUX.

The previous lineinfile-with-backrefs negative-lookahead regex was
not appending NVIDIA parameters when missing. Switch to a clearer
approach: slurp the file, extract the current GRUB_CMDLINE_LINUX
value, build a merged target value that appends missing NVIDIA
params, then write back the line. lineinfile sees no diff when the
target matches the current line, preserving idempotency.

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).
