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.

Introduces optional per-clone IP assignment using the Firecracker Microvm
Metadata Service (MMDS). A background daemon (fc-net-init) is baked into
the rootfs during init and captured in the golden snapshot — on clone
resume it polls 169.254.169.254 and applies the IP/GW/DNS config injected
by the orchestrator immediately after snapshot restore.
- config.go: add AutoNetConfig bool (FC_AUTO_NET_CONFIG=1)
- orchestrator.go: embed fc-net-init daemon + MMDS link-local route in
init script; set AllowMMDS: true on golden NIC; spawnOne/SpawnSingle
accept net bool and propagate it via FC_AUTO_NET_CONFIG in proxy env
- console.go: set AllowMMDS: true on clone NIC; call configureMmds()
after m.Start() when AutoNetConfig is enabled
- network.go: add configureMmds() — PUT /mmds with ip/gw/dns over the
clone's Firecracker Unix socket
- serve.go: POST /clones accepts optional {"net": bool} body to override
the global AutoNetConfig default per-request
- web/terminal.html: spawn button always sends {"net": true}
- docs/commands.md: document manual config + MMDS autoconfiguration

- Add docs/commands.md with per-command purpose, step-by-step shell/SDK
call sequences, config tables, outputs, and error conditions
- Rename module from github.com/you/fc-orchestrator to github.com/kacerr/fc-orchestrator
- Add KernelURL field to Config so the download URL is configurable via
FC_KERNEL_URL instead of being hardcoded in Init()
- Expose FC_KERNEL_URL in the usage string
- Add verbose logging of dd/mkfs.ext4/mount/tar calls in buildRootfs
