    x11-wm/blackbox: fix build with libc++ 19
    
    As noted in the libc++ 19 release notes [1], std::char_traits<> is now
    only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
    instantiation for other types will fail.
    
    This causes x11-wm/blackbox to fail to compile with clang 19 and libc++
    19, resulting in errors similar to:
    
      /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned int>'
        820 |   static_assert(is_same<_CharT, typename traits_type::char_type>::value,
            |                                          ^
      ./Menu.hh:82:13: note: in instantiation of template class 'std::basic_string<unsigned int>' requested here
         82 |     ustring lbl;
            |             ^
      /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here
         23 | struct _LIBCPP_TEMPLATE_VIS char_traits;
            |                             ^
    
    This can be fixed by defining `Uchar` as `char32_t` instead of `unsigned
    int` in `Unicode.hh`.
