vibesql-executor 0.2.0

//! GROUP BY operations and aggregate function evaluation
//!
//! This module provides:
//! - Aggregate function accumulators (COUNT, SUM, AVG, MIN, MAX)
//! - Hash-based grouping implementation
//! - ROLLUP, CUBE, and GROUPING SETS expansion
//! - SQL value comparison and arithmetic helpers
//! - Specialized GROUP BY key types for efficient hashing
//! - Parallel aggregation using Sink/Combine/Finalize pattern (Issue #4132)
