signal-mod vs mod-signal vs philiprehberger-safe-shutdown

Cross-platform OS signal handling and graceful-shutdown orchestration for Rust. One API for SIGTERM, SIGINT, SIGHUP, SIGQUIT, SIGPIPE, SIGUSR1, SIGUSR2 and the Windows console control events, with cloneable observer and initiator handles, priority-ordered shutdown hooks, and optional adapters for the Tokio and async-std runtimes.

Unified OS signal handling for Rust. SIGTERM / SIGINT / SIGHUP / SIGPIPE and Windows equivalents through one API. Graceful shutdown orchestration with priority ordering, timeout enforcement, and hook chaining. Replaces the patchwork of ctrlc + signal-hook with a clean runtime-agnostic substrate.
