Detection only ever considered builds that finished, so a build wedged on a
network call was invisible: no incident, no issue, no alert, while it held one
of the five Jenkins agent slots. Observed on metis build 272, which sat on
apt-get update for 75 minutes and starved the triage demo of an agent with
nothing anywhere saying so.
A build still running past ARIADNE_HERMES_HUNG_BUILD_MINUTES (default 45) now
files an issue and lands human_required. No model is consulted: the console is
still being written, so a root cause would be invented. Escalates once per
build, and a cap of zero disables the check.
