Run 6 stalled in setup-host.sh, which should be seconds on a host that
already has incus. The ordering was wrong: cleanup ran AFTER setup, so
setup-host reconfigured claudenet's ACLs while an aborted run's boxes
were still attached to that network — 'incus network set' then has to
push the change onto every live NIC. The same aborted run also left the
D-phase mutations (dns.mode=none, NIC filtering) in place, so setup was
converging against a moving target.
Boxes are now deleted and the mutations reverted first, so setup-host is
the no-op it should be. It is also bounded (5 min) and, on timeout,
prints the three things worth checking instead of hanging: instances
still on the network, the firewall unit, the incus daemon. Every cleanup
call gets its own timeout, so a wedged instance cannot stall the run
before the drill has printed a single line.
RUNS.md gains this as trap 8.
