reExec replaces the process image via execve(2). Same PID, so the parent shell waits on one process throughout, one continuous session. Success never returns; only exec failure (missing binary, wrong arch, no exec bit) surfaces as the error. Windows lacks execve and uses a spawn-and-wait fallback fo

(exe string, args []string, env []string)

// surfaces as the error. Windows lacks execve and uses a spawn-and-wait
// fallback for the same effect.
func reExec(exe string, args []string, env []string) error {
	return syscall.Exec(exe, args, env)
