Run 32118850138 lost the :53 listener, so the sampler counts listeners.
Run 32538854067 lost DNS with the listener still bound: sockets-udp.txt
showed dnsmasq holding 0.0.0.0:53 while every forwarded query timed out,
and the sampler reported that hour as healthy.
Each tick now also records what a glibc caller gets back — for the zone
this resolver owns, derived from its own address= line, and for one name
it must forward — with the latency that caller paid. The rescue collector
probes the in-zone name too: probing external names alone cannot separate
"forwarding is gone" from "dnsmasq is gone".
The sampler now also runs on the swarm lab DNS nodes; it only ever ran in
the compose path, which is why the Magento artifact carried no sampler log
at all. Its location comes from group_vars FILE_DNS53_SAMPLER_LOG and is
required at every call site, so a run cannot quietly collect nothing.

container.py hardcoded /tmp/infinito-rescue-diagnostics, a second copy of
DIR_RESCUE_DIAGNOSTICS from group_vars/all/05_paths.yml. Move the value to
a generated env key so the paths SPOT stays single: a new handler seeds
INFINITO_RESCUE_LOCAL_DUMPS_DIR from read_group_path(), recurse() forwards
it into nested runtimes, and an unset key now prints why the in-play role
dumps are missing rather than silently collecting nothing.
Registers the handler in ORDERED_HANDLERS - the registry is explicit, not
discovered - and moves rescue_diagnostics_dir.py into the new rescue/
package so the two siblings satisfy the prefix-group lint.
