warm: self-heal wedged dnsmasq, run after deploy, shared state dir
dnsmasq adds IPs to an nft set only on a fresh upstream reply; a cache
hit never refreshes the set. On Archie the :5350 instance also wedged:
TCP child processes first, then the main process, logged
'nftset ... netlink: Error: cache initialization failed: Protocol error'
on every add and stopped filling bbrkn_v4/v6 until restarted.

warm-nftset.sh now counts those errors for the main PID during the run
(journalctl _PID=) and, if any, restarts the service and warms again;
exit 1 if it still fails. The state dir defaults to /var/lib/bbrkn so the
root cron job and the deploy share one lock (LOCK_WAIT lets deploy wait).

deploy-to-gateway.sh runs the warmer right after flushing the sets,
since clients keep old IPs cached and would bypass the tunnel until the
next fresh resolve. A warm failure only warns; it does not roll back.
