feat: custom boot branding, MBR fix, Plymouth theme, CI smoke tests
Boot fix: - Ship proven Debian Live MBR (4552) as branding/isohdpfx.bin — the ISOLINUX package MBR (33ed) doesn't boot on all hardware. This was the root cause of "machine doesn't pick up the USB". Branding: - Custom GRUB background: pixel-art floating island (1024x574) - Archipelago pixel-art logo for Plymouth boot splash - GRUB theme: dark background, orange selected item, no broken font refs - Plymouth theme: script-based with progress bar, LUKS prompt support - Plymouth + splash added to target rootfs packages - GRUB theme installed on both installer ISO and target system - Serial console (ttyS0) added to kernel params for QEMU debugging CI improvements: - Smoke test step: mounts ISO, verifies all critical files, checks initrd has live-boot, confirms boot=live in grub.cfg. Fails build before copying to Builds if any check fails. Dev workflow: - dev-branding.sh: extract ISO, swap branding, repackage, boot in QEMU (~10 seconds vs 20 min full rebuild) - generate-grub-background.py: procedural cyberpunk background generator - generate-plymouth-logo.py: procedural logo generator - Improved test-iso-qemu.sh: --bios/--nographic flags, serial logging Build: - Simplified live-boot install (clean chroot, no complex fallbacks) - Static branding images preferred, generators as fallback Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
