A done-callback on run_control()'s task logs the traceback at the death and
sets `stop`; amain() runs the ordinary wind-down (shutdown() ->
command_site_zero()) and main() exits 70 (EX_SOFTWARE). Normal stops and
run_control()'s refusal path are ignored by the callback (still 0 / 78).
hass.py: a malformed JSON body, a JSON non-object, and an undecodable error
body are an absence / a failed write, not an exception into the loop.
checks() gains a first "control loop" row, red past FIRMWARE_INGEST_VETO_S.
Why exit rather than restart in-process, and what the Supervisor actually
does on exit (restarts only with the per-install Watchdog toggle on, default
off): DECISIONS/SAFETY-61-control-task-death.md.
