How BepInEx Loads via Doorstop (The Reference Architecture)

Unity Doorstop is a DLL proxy that intercepts the game's startup to load managed assemblies (like BepInEx) before Unity scripts run. Here's the chain:

DLL Proxying: A proxy DLL (winhttp.dll, version.dll, or winmm.dll) is placed in the game's root directory. When the game EXE starts, Windows loads the proxy instead of the real system DLL.
Configuration: Doorstop reads doorstop_config.ini from the same directory as the game EXE (the game's working directory/install folder). It expects:
INI

[UnityDoorstop]
enabled=true
targetAssembly=BepInEx\core\BepInEx.Preloader.dll

Assembly Loading: Doorstop locates the targetAssembly path and loads it into the Mono/IL2CPP runtime before the game's scripts execute.
BepInEx takes over: BepInEx.Preloader.dll patches Harmony, loads plugins from BepInEx/plugins/, etc.

Critical requirement: Doorstop resolves paths relative to the game executable's directory (where the proxy DLL sits), unless an absolute path is used for targetAssembly.
