    Close item 83: terminate callback + single-fire set_terminate

    Add dssh_terminate_cb and dssh_session_set_terminate_cb() so the
    application can close sockets or signal its event loop when the session terminates, unblocking I/O callbacks that would otherwise cause dssh_session_cleanup() to hang on thrd_join.

    Make dssh_session_set_terminate() single-fire via atomic_exchange --
    previously it unconditionally re-broadcast all condvars on every call.
    The callback fires exactly once, before condvar broadcasts, from
    whichever thread triggers termination.

    Update I/O callback documentation to state that callbacks MUST return
    promptly when dssh_session_is_terminated() is true. Update client.c
    and server.c to use shutdown(fd, SHUT_RDWR) in the terminate callback.
