KaifAhmad1 d056e47ab7 feat(kg): add KnowledgeGraph dataclass and native KGVisualizer support (#471) ...

- Add semantica/kg/knowledge_graph.py with KnowledgeGraph dataclass
  (entities, relationships, metadata) plus __len__ and __bool__ helpers
- Export KnowledgeGraph from semantica/kg/__init__.py
- Add KGVisualizer._convert_knowledge_graph() for explicit, non-mutating
  conversion from KnowledgeGraph to internal dict format
- Route isinstance(graph, KnowledgeGraph) through _convert_knowledge_graph
  inside _normalize_graph so all five visualize_* entry points accept
  KnowledgeGraph directly without any manual conversion
- Add TestFormalKnowledgeGraphType (15 tests)

Closes #471
