Add a new script that prepares FWS to boot signed under Secure Boot without enabling kernel lockdown, preserving hibernation capability. The script: - Checks UEFI firmware availability - Installs sbctl if needed - Locates ESP and GRUB EFI binary - Reinstalls GRUB with SBAT section if missing - Creates and enrolls sbctl keys while preserving Microsoft keys - Signs GRUB and available kernel images - Provides instructions for manual firmware setup steps - Enables automatic re-signing after kernel/GRUB updates via pacman hooks This allows FWS to meet Vanguard's Secure Boot requirement without sacrificing hibernation support.
