Enable optionally starting LUAZIP apps without an attached console window

[rdw-software]

I'm not actually sure if this is desirable for Linux and macOS, nor how user expectations are on those platforms. But on Windows:

• It's conceivable you'd want to create a "native" app that spawns one or multiple windows
• For example, 3D rendering with WebGPU inside a GLFW context (or even just a WebView)
• Running this from the CLI obviously requires a console/terminal, which is fine for development or debugging
• However, once built into a standalone executable, it would be desirable to have the option of hiding this window
• At compile time, it generally can be done by adding a WinMain function, although that's a bit awkward in this context
• A better approach would be to hide the console window when running from a LUAZIP app, using platform APIs

Not sure if this will work without briefly showing a terminal if done via Win32 APIs? If so, may need a different approach.
