The mesh's one resolver, what every node asks, and a node's hosts file (hq ADR 0194, 0196, 0199)

- dnsmasq holds mesh-dns-resolver: provides wildcard-resolution mesh-wide, forwards every declared zone (zones fact), listens on the private address and loopback only, reads no hosts file and no operator's files, and no longer writes the container runtime's dns. - resolv-conf names the mesh's resolver by address, then 1.1.1.1, timeout 1, one attempt; it now holds the runtime's live-restore, which dnsmasq held and every node needs. - resolved-split-dns routes the suffix to the mesh's resolver by address, not 127.0.0.1. - hosts: new module holding node-hosts-file — the machine's own lines in its block of /etc/hosts, the operator's lines kept, changed by entries/add/remove through sudo -n.
