New section between base and DE menus:
- 'Disable SELinux permanently?' — default no; writes SELINUX=disabled with a
backup, warns about the security tradeoff.
- When / is btrfs: 'snapper + grub-btrfs + compression?' — default yes. Shows
subvolume list + fstab, appends ,compress=zstd:1 to btrfs fstab entries that
lack a compress= option (idempotent, fstab backed up), then runs the
SysGuides sysguides-snapper-fedora installer (snapper root+home, grub-btrfs,
DNF5 pre/post snapshot actions).
- Flags for unattended runs: --selinux=keep|disabled, --snapper=yes|no.
- Fix found by the harness: the flag initializers sat after the arg loop and
wiped parsed values; --snapper=no was silently ignored. Initializers moved
before the loop.
README + section renumbering updated.
