//! Lock test helpers shared across integration tests.
//!
//! Responsibilities:
//! - Provide short-lived process utilities for lock-related tests.
//!
//! Not handled here:
//! - Lock acquisition logic or filesystem operations.
//! - Assertions about lock behavior.
//!
//! Invariants/assumptions:
//! - Spawns the current test binary with `--help` and waits for exit.
//! - Returned PID should be treated as stale immediately after the process exits.
