#ProcessOutputHandler

Observed use:

• Process::OutputReceived and Process::ErrorReceived raise one argument containing raw output bytes.
• The wrapper forwards a winrt::array_view<const uint8_t> produced from the C callback buffer.

process.OutputReceived([](auto const& data)
{
    std::string text(data.begin(), data.end());
    printf("stdout: %s\n", text.c_str());
});
