Add disko as a flake input (following nixpkgs) and wire its NixOS module into the host-builder, so any Host can declare a disk layout while the layout itself stays a per-Host concern. neogaia's layout (hosts/neogaia/disk.nix): one GPT NVMe disk with a systemd-boot EFI system partition and a LUKS container holding btrfs with @root/@home/@nix subvolumes. The initrd prompts for the passphrase on a normal boot. Swap is RAM-backed zram, so there is no on-disk swap partition; zramSwap is enabled directly for now (task 0003 lifts it into a toggle Module). The task-0001 placeholder fileSystems are removed since disko now derives them.
