feat: Promote "extends" to "implements" for class-to-interface relationships in edge creation

Browse Source 
Addresses semantic accuracy in inheritance relationships where classes use "extends" syntax to implement interfaces. Adds target node inspection to detect interface/protocol targets and promotes the edge kind from "extends" to "implements" when the source is a concrete class or struct, ensuring proper representation of implementation vs inheritance relationships in the code graph.
