Five info-level log points across the WS lifecycle helper:
ws_open_attempt / ws_open_ok / ws_hello_sent / ws_hello_acked /
ws_closed (with status + close code/reason).
Surfaced during M1 smoke testing — without these the only visible
signal was "presence row missing on broker," which made it hard to
distinguish "WS never opened" / "opened but hello rejected" /
"acked then closed by broker."
Both clients prefix the helper-emitted msg ("session_broker_*",
"broker_*") so log greps stay clean per role.
