* Degrade instead of crashing when the interop assemblies are missing
OnInvokeMethod references interop types (UnityEngine.Application/LogType) in its body. The CLR JIT-compiles the whole method before running any of it, so when the interop assemblies cannot be resolved the method throws FileNotFoundException at JIT time -- before its own try is entered -- and the exception escapes into the native runtime-invoke detour and crashes the process with nothing logged.
Move the interop-referencing call into its own SetupUnityLogging method called inside the try. OnInvokeMethod then JITs without the interop assemblies present, the missing-interop failure is caught, and the loader degrades (logs and continues) so the game runs unmodded. Set unhook at the top of the try so the detour fires exactly once even on failure.
* Condense the interop-degrade comments and reword the fatal log
Per review: trim the JIT-bypass comments to one line each and change
the fatal message to "Unable to execute IL2CPP chainloader, no plugins
will be loaded".
Assemblies are often loaded on the il2cpp side but not on the mono side, causing confusion when using reflection.
This will load all interop assemblies right before plugins are loaded, which should mostly avoid these issues at a low time cost of around 40ms.
