Adds modules/disko/baremetal.nix: two disks, each its own top-level zpool vdev with no mirror/raidz between them (disko's zpool `mode` defaults to "" for a plain stripe), ESP + systemd-boot on disk1. Device paths are placeholders in variables.nix (guiRootDisk1/guiRootDisk2) until the real hardware profile arrives. Verified structurally by building a throwaway nixosSystem with the actual disko.nixosModules.disko and reading the generated system.build.formatScript: it emits `zpool create rpool ... disk1 disk2` with no mirror/raidz keyword, confirming a genuine stripe. Not yet wired into any flake target -- that happens once the hardware config lands and a new bare-metal platform module is added, per the agreed sequencing.
