The aarch64 packages removed etc/mkinitcpio.conf.d and
etc/limine-entry-tool.d wholesale. On an encrypted aarch64 install that boots
with Limine (DGX Spark, Snapdragon X), installing the published package
therefore drops omarchy_hooks.conf, HOOKS falls back to /etc/mkinitcpio.conf,
and the next kernel update builds an initramfs with no encrypt hook: the
machine hangs waiting for /dev/mapper/root with no prompt.
Ship both drop-in directories on aarch64 and remove only
thunderbolt_module.conf, whose module ARM kernels do not have. Keep the
Limine template and the snapper notifier autostart for the same reason. The
memory-stack removals (zram, oomd, zswap, USB autosuspend) are unchanged.
