Build me a Windows C plus plus project that works as a drop in replacement for steam_api.dll and steam_api64.dll for Steam games. I want it to spoof the game as Spacewar by default, but let me change the AppId with a simple union-crax.ini file next to the game exe. It should also support an optional original AppId for overlay assets, optional encrypted app ticket emulation, optional SteamStub patching for games that need it, and a basic DLC unlock list from the ini.

Please make it easy to build in Visual Studio 2022 with simple batch files for x86 and x64 output, and make sure the built dlls land in obvious build folders. I also want a plugin loader that loads dlls from a plugins folder in alphabetical order, plus a tiny plugin ABI so plugins can initialize after SteamAPI_Init and clean up on shutdown.

Keep the core focused on generic Steam side spoofing and config handling. If you need details, look up current Steam API and Visual Studio docs online.
