Adds the five missing worker units plus a grouping target so `systemctl start decnet.target` brings the whole fleet up in order. Sniffer gets CAP_NET_RAW for scapy; collector and mutator join the docker supplementary group for docker.sock access. Repoints Documentation= across all existing units to the canonical git.resacachile.cl wiki.
