Module query 

Query execution engine for CQLite

This module provides the core query execution engine that bridges between CQL parsing and the storage engine. It includes:

• CQL query parsing and validation
• Query planning and optimization
• Query execution with storage integration
• Prepared statement support
• Result set management
• REVOLUTIONARY SELECT parser for direct SSTable access
