Module executors 

Multi-Mode Query Executors

Specialized executors for each query language mode:

• Gremlin: Traverser-based execution with path state tracking
• SPARQL: Pattern matching with variable bindings
• Natural: Translation + execution with explanation
• Vector: HNSW-based similarity search with metadata filtering
• Hybrid: Combined structured + vector search with fusion strategies

Each executor converts its native AST to execution operations, leveraging the unified executor for common operations.
