The three fork() callers run Rust code in the child before exec/exit, which is only safe while the process is single-threaded. Add a small runtime check (panics in debug, warns in release) before each fork and SAFETY comments documenting the invariant. Also annotate the truncated clone3_args struct so its short prefix isn't mistaken for a bug.
