• Unix: a SIGINT handler writes one byte to a self-pipe; [ctrl_c] awaits readability on the pipe through the runtime’s epoll/kqueue driver. No polling.
• Windows: SetConsoleCtrlHandler routes console events through a future-based interface.
• WASM: host import [crate::abi::imports::signal_wait] drives the completion.
