The 60s/5-reconnect window from the original fix could never actually
fire: consecutive reconnect attempts are never closer together than one
summary poll interval (30s) plus the 5s reconnect pause, so at most ~2
timestamps can ever land inside a 60s window regardless of how unhealthy
the connection is. That silently downgraded every reconnect to INFO
permanently, including the persistently-broken case the change was
supposed to still surface at WARNING.
Widen to a 300s window with a threshold of 3, which is reachable under
sustained failures and still a reasonable proxy for the README's
"actually broken" case.
