[beta]High-performance SQL parser and AST analyzer written in TypeScript. Provides fast parsing and advanced transformation capabilities.

 * CTENormalizer is responsible for normalizing Common Table Expressions (CTEs) within SQL queries.
 * It collects all CTEs from various parts of the query and consolidates them into a single WITH clause
 * at the root level of the query.
 *
 * This implementation uses:
 * 1. CommonTableCollector - to gather all CTEs from the query structure
 * 2. WithClauseDisabler - to remove all original WITH clauses from the query
 * 3. CTENameConflictResolver - to resolve name conflicts among CTEs and sort them properly
