14//! Transaction management and locking for Noxu DB.
15//!
16//! transaction management and
17//! record-level locking with deadlock detection.
18//!
19//! ## Phase 3: Lock Type System Foundation (Implemented)
20//!
21//! - Lock types, conflict and upgrade matrices
22//! - Lock grant types and results
23//! - Write lock info for undo operations
24//! - Lock statistics
25//! - Locker hierarchy (BasicLocker, ThreadLocker, HandleLocker)
