//! Expression optimization module for query planning
//!
//! This module implements:
//! - Constant folding and dead code elimination for expressions
//! - WHERE clause predicate pushdown for efficient join evaluation
//! - Cost-based predicate ordering for optimal filter performance
//! - Centralized index planning and strategy selection
//! - Subquery rewriting for IN predicate optimization
//! - Scalar subquery decorrelation for aggregate patterns (issue #4760)
//! - Adaptive execution model selection (row-oriented vs columnar)
//! - Aggregate-aware query optimization for GROUP BY/HAVING performance
//! - Unused table elimination for cross join optimization
//! - Column pruning for post-join processing optimization (#4355)
//! - DISTINCT elimination when unique index + NOT NULL guarantee uniqueness (#4852)
