ralph-agent-loop 0.4.0

//! Purpose: guard macOS contract scripts against teardown regressions.
//!
//! Responsibilities:
//! - Verify noninteractive RalphMac contract scripts clean up launched app processes.
//! - Verify those scripts remove disposable temp roots and fail loudly on lingering apps.
//!
//! Scope:
//! - Static contract assertions over repo shell scripts only.
//!
//! Usage:
//! - Run `cargo test --test macos_contract_script_cleanup_test`.
//!
//! Invariants/Assumptions:
//! - Script text is treated as the public contract for repo-owned cleanup behavior.
