//! Stub implementations for extern "C" locking functions.
//!
//! When building as a cdylib (e.g., for NAPI, Python, Go, .NET),
//! the locking functions are not provided by a C caller.
//! This module provides no-op stub implementations to satisfy the linker.
//!
//! For C FFI builds (staticlib/cdylib with C caller), the actual
//! implementations are expected to be provided by the C application.

/// No-op stub for pool lock (used when no external C caller provides it).
