feat(heidenhain): Part 9 condition class from alarm class/group, ALARM: selectors in the browse picker, unclaimed alarms counted + logged (#839)
- Core: optional AlarmEventArgs.ConditionClass (AlarmConditionClass Base/Process/Maintenance/System/Safety)
carried by NativeAlarmProjector on AlarmConditionSnapshot and written to ConditionClassId/Name by
OtOpcUaNodeManager (kept across class-less events, carried across a #641 rebuild).
- Heidenhain: HeidenhainAlarmClasses — HEIDENHAIN DNC-interface class/group names (corroborated by the
captured iTNC 530 record); class 5 => Safety, group 1/2 => Process, 4/5 => System, else Base.
- DiscoverAsync offers AlarmConditions/ selector leaves (IsAlarm Boolean); browse-commit seeds the alarm object.
- Alarms no selector claims: otopcua.driver.alarms.unmatched counter, /hosts diagnostics, rate-limited Warning.
