//! Purpose: thin integration-test hub for `ralph::fsutil` contract coverage.
//!
//! Responsibilities:
//! - Re-export shared imports and suite-local synchronization used by fsutil integration tests.
//! - Delegate temp cleanup, atomic write, and tilde expansion coverage to focused companion modules.
//!
//! Scope:
//! - Integration tests for the public `ralph::fsutil` facade only.
//!
//! Usage:
//! - Companion modules use `use super::*;` to access shared imports and `ENV_LOCK`.
//!
//! Invariants/Assumptions:
//! - This root module contains no test functions.
//! - Test names, assertions, and environment-lock semantics remain unchanged from the pre-split suite.
