Auto-managed PR — Mode B (autonomous)

Driver: twincat Phase: 1 Plan PR: 1.2
Plan: docs/plans/twincat-plan.md
Effort: M Cross-driver: False

Summary

Stop marshalling IEC TIME/DATE/DT/TOD as raw UDINT; convert to native UA Duration/DateTime via post-processing in ReadValueAsync, ConvertForWrite, OnAdsNotificationEx. May expose Duration in DriverDataType.
