fix(alerts): краш при restart-политике, гистерезис закрытия, редкие правки

Найдено смоуком на живых контейнерах (examples/, #19):
- контейнер с restart: on-failure поднимается за секунду — между раундами
  его не видно в exited; краш теперь распознаётся и по росту RestartCount
  (сравнение со снапшотами до текущего раунда), повторы — счётчик
- алерт закрывается, только когда условия нет resolve_after (60 с): иначе
  флапающий сервис получал бы «✅ восстановлено» после каждого раунда
- правки сообщений со счётчиком — не чаще раза в минуту на алерт
