Pull request overview
Improves NGAP UE context release handling around handover/stale RanUe scenarios, and tightens AmfUe↔RanUe attachment behavior to reduce incorrect detaches.
Changes:
- Remove RanUe contexts on UEContextReleaseComplete when the associated AmfUe is missing, and add a “stale RanUe” guard to avoid detaching the current RanUe.
- Add unit tests for stale RanUe removal and handover target promotion on UEContextReleaseComplete.
- Adjust
AmfUe.AttachRanUebehavior and refactor log updates into a helper.
