feat: vmtest.sh: the boot loader test for every loader the ISO advertises
One VM per loader, Steam Machine (--fremont): Steamify's state as its menu sees it, OS name untouched, loader identity, the DKMS modules for every kernel, Steamify's loader-specific code (hdmi_remove_boot_param), a kernel update, and a reboot into each of the two kernels. Headless by default with a log Konsole (--window shows the VMs). Fails when an advertised loader has no test. Limine 41, systemd-boot 40, GRUB 40 checks pass.
