anti f21453afdc chore(systemd): add units for collector/profiler/sniffer/prober/mutator + decnet.target
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.

# Deliberately NOT After=decnet-agent.service — the updater must come up even
# when the agent is broken, since that is exactly when it is most useful.

# The updater SIGTERMs the agent and spawns a new one. Same User=decnet means
# signalling is allowed without CAP_KILL. It does not need NET_ADMIN/NET_RAW
# itself — the new agent process picks those up from decnet-agent.service when
# systemd restarts it (or from the agent's own unit's AmbientCapabilities when
# spawned by the updater as a direct child).
