s7cmd 1.2.1

//! Process-level e2e tests for graceful Ctrl+C handling.
//!
//! Each test spawns the binary directly (NOT via cargo run — cargo
//! intercepts SIGINT), gives it ~1.5s to enter its work loop, sends SIGINT,
//! and asserts the child exits with code 130 within a 30s timeout.
//!
//! Unix-only: SIGINT delivery via the `nix` crate.
