feat: Add hasParent and getDistance to ComponentManager

Closed v11.23.0/archive-v11-23-0-chunk-2 enhancementaicore

tobiu commented on Jan 20, 2026, 1:21 AM

Porting useful helper methods from feat/8814-race-condition to the dev branch.

Added methods to Neo.manager.Component:

hasParent(childId, parentId): Boolean check if a component is a descendant of another.
getDistance(childId, parentId): Returns the generational distance (1-based) between child and parent.
