//!
//! transaction management and
//! record-level locking with deadlock detection.
//!
//! ## Phase 3: Lock Type System Foundation (Implemented)
//!
//! - Lock types, conflict and upgrade matrices
//! - Lock grant types and results
//! - Write lock info for undo operations
//! - Lock statistics
//! - Locker hierarchy (BasicLocker, ThreadLocker, HandleLocker)
