Aiden McClelland 3024db2654 feat: add GRUB installer USB boot detection via configfile ...

Install a /etc/grub.d/07_startos_installer script that searches for a
.startos-installer marker file at boot. When found, it creates a
"StartOS Installer" menu entry that loads the USB's own grub.cfg via
configfile, making it the default with a 5-second timeout.

Uses configfile instead of chainloader because on hybrid ISOs the
.startos-installer marker and /boot/grub/grub.cfg are on the ISO9660
root partition, while the EFI binary lives on a separate embedded ESP.
chainloader would look for the EFI binary on the wrong partition.
