Add Limine + Snapper support (#998)

* Persist urgent notifications

* Create omarchy-snapshot

* Create snapshot before pulling

* Extract alternative bootloader configs

* Add limine-snapper config

* Fix check

* Update login scripts

* Make chroot friendly

* Extract cmdline instead of using blkid due to error

* Add restore command

* Export $TERMINAL so we get clickable restore notifications

* Remove sync -- causes errors...we have nothing to sync yet

* Executable

* Minor cleanup and compatibility for non-ISO

* Give login its own section

* Give no-arg guard and inline commands
