Query Engine - Unified query interface for memory data

The QueryEngine provides a unified interface for querying memory snapshot data, supporting various query types and filtering options.

Key properties:

• Unified: Single interface for all query types
• Efficient: Optimized for fast query execution
• Flexible: Supports filtering and sorting
