//! Optimizer Module Tests
//!
//! Test coverage:
//! - Heuristic optimization rules
//! - Cost-based optimization strategies
//! - Cost estimation and selectivity
//! - Statistics management
//!
//! These tests focus on optimizer internal correctness, complementing
//! the end-to-end optimizer tests in tests/dql/optimizer.rs
