Major ISO build overhaul on dev-iso branch:
- Replace ~800MB Debian Live download with debootstrap --variant=minbase
(~150MB installer squashfs built from scratch)
- Custom initramfs with archipelago-mount hook for boot media detection
- Systemd service auto-starts installer (replaces profile.d hack)
- GRUB + ISOLINUX configs written from scratch (no Debian Live dependency)
- EFI boot image built with grub-mkimage (no more MBR extraction)
- Archipelago GRUB theme: dark background, Bitcoin orange accents
- Theme installed on both installer ISO and target system
- Rootfs optimizations: --no-install-recommends, strip docs/man/locales,
remove firmware-misc-nonfree/wget/htop, add explicit font deps
- Separate CI workflow (build-iso-dev.yml) for dev-iso branch
- Includes pre-existing fixes from main (build-iso.yml, middleware, Login)
Target: sub-2GB unbundled ISO (down from 3.9GB)
