Module terminal 

Terminal control and job control for interactive mode.

Handles process group management, terminal ownership, and foreground wait with WUNTRACED support for Ctrl-Z (SIGTSTP).

All functionality is #[cfg(unix)] — non-Unix platforms get stubs.

Signal disposition (sigaction) requires unsafe per POSIX. This is the only module in kaish that uses unsafe code, and it’s limited to well-understood signal-handling patterns that every shell must perform.
