v0.1.1-beta — console login + verified wifi & ufw

Blueberry Linux v0.1.1-beta

Second beta. Fixes and verification since v0.1.0-beta:

• Console/serial login fixed — agetty couldn't exec /bin/login
  (merged-usr gap) and login(1) had no /etc/login.defs; both fixed. TTY
  and serial login now work (graphical SDDM login already did).
• WiFi verified working — NetworkManager (nmcli 1.50, nmtui),
  wpa_supplicant 2.11 and the full linux-firmware set. Tested live: NM
  starts, manages and connects an interface.
• Firewall (ufw) working — kernel gained the legacy netfilter/iptables
  tables (NETFILTER_XTABLES_LEGACY); ufw enable now installs and enforces
  rules. Tested live: default-deny incoming with an allow rule active.

Images (BIOS + UEFI, all boot into the TUI installer):
