feat(archiso): auto-start guided installer on boot, use answerfile for unattended mode 

.zlogin execs .automated_script.sh on login, which checks for /answerfile.json;
if present it runs the auto installer (passing the path), otherwise launches the
guided installer directly — no manual invocation needed.
