    Delete dead x11 type_len==2 check (bug 6)

    The check `type_len == 2 && memcmp(ctype, "x11", 3)` compared
    3 bytes against a 2-byte string Ä could never match. The x11
    rejection is fully handled by the type_len==3 check.

    Fix channel ID collision on uint32_t wrap

    alloc_channel_id() now scans the active channel table to skip
    IDs already in use. Returns DSSH_ERROR_ALLOC if all 2^32 IDs
    are exhausted (the application has made some terrible mistakes).

    Fix send_channel_request_wait race: CLOSE clobbering successful response

    When the server accepted a channel request (CHANNEL_SUCCESS) and then immediately closed the channel (CHANNEL_CLOSE), the client's demux
    thread could process both messages before the client thread woke up.
    The post-loop check `if (sess->terminate || ch->close_received)` then
    returned DSSH_ERROR_TERMINATED even though request_responded was true, discarding the successful response and causing dssh_chan_open to return
    NULL.

    Fix: capture `responded` under buf_mtx; only return TERMINATED when
    the loop exited without getting a response. If the server explicitly
    answered, honor that answer regardless of close_received.

    Observed as test_self_exec_exit_code failing under -j16, predominantly
    with RSA variants where keygen CPU contention widens the scheduling
    window between the two demux dispatches.
