When the operator clicks Start vetting and the host is heartbeating,
the heartbeat response now carries cmd=reboot_for_vetting + run_id.
The handler drives the Queued → WaitingWoL transition via the existing
state machine, so a benign race with the 2s dispatcher poll is refused
by the state machine (not double-dispatched). WaitingWoL retries for
10 minutes to cover a crashed-mid-reboot case, then falls back to
operator action.

vetting-agent gains a `host` subcommand that runs as a systemd service
installed by the quick-register one-liner, POSTing every 30s to
/api/v1/hosts/{mac}/heartbeat so the dashboard tile shows "online" or
"Nm ago" without waiting on WoL. Ships dormant client code for the
Phase 2 reboot_for_vetting command so the server can flip it on later
without a binary redeploy.
