#638 gave omarchy-settings this and -dev was never ported, so edge, the only
channel aarch64 machines are qualified for, still stripped zram, oomd, zswap,
the sysctl tuning and USB autosuspend there: on Snapdragon, migration
1790328426 installs zram-generator, finds no dev-zram0.swap and completes
without zram. A source with default/settings-runtime-profile now gets the same
files, backup and optdepends on aarch64 as on x86_64, Thunderbolt drop-in
included, and its HOOKS files ship as they are. Older sources, including the
current quattro pin, keep today's aarch64 package. The platform guard and its
detector check stay aarch64-only (#691, #694). The keyboard backlight unit
first-run enables ships whenever the source has it, as in omarchy-settings.
tests/settings-runtime-profile.sh now runs both recipes. pkgrel 5 so the
recipe change builds; the payload from the current pin is unchanged.
