Add Alpine, Debian, and Ubuntu rootfs support to `init [distro]`. Golden snapshots are now namespaced under `golden/<tag>/` so multiple baselines can coexist. `spawn [tag] [N]` selects which snapshot to clone from. Systemd-based distros (Debian, Ubuntu) get a fc-net-init systemd unit; Alpine keeps its inittab-based init. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
