 * A specialized table source collector designed for CTE dependency analysis.

 * - Always includes CTE references in results (treats CTEs as valid table sources)
 * - Always performs deep traversal of subqueries, WHERE clauses, etc.
 * - Is optimized for dependency analysis rather than database schema analysis
 *
 * This collector is specifically designed for use by CTEDependencyAnalyzer to track
 * which tables/CTEs are referenced by queries at any nesting level.
