feat: add dual-mode ISO builds (production vs demo) with serial console
Two build modes: - `./run.sh iso` — production ISO (prompts for credentials, quiet boot) - `./run.sh iso:demo` — demo/CI ISO (hardcoded test credentials, serial console output, verbose kernel) Changes: - run.sh: Accept iso:demo subcommand, pass KNEL_BUILD_MODE to Docker - run.sh: Demo mode uses verbose kernel cmdline with console=ttyS0 - config/bootloaders/grub-pc/config.cfg: GRUB serial console on ttyS0 at 115200 baud alongside VGA gfxterm (dual output) - config/includes.installer/demo.preseed.cfg: Fully automated preseed with hardcoded test credentials (NOT for production use) - config/hooks/binary/0199-serial-console.hook: Ensures serial console on Debian installer entries too - .gitignore: Fix binary/ pattern to /binary/ (was matching config/hooks/binary/) Demo credentials (TESTING ONLY): - User: football / Kn3l-F00tball-D3m0! - Root: Kn3l-R00t-D3m0! - LUKS: Kn3l-D3m0-LUKS! 💘 Generated with Crush Assisted-by: GLM-5.1 via Crush <crush@charm.land>
