💡 What: Replaced slow UnityEngine.Object.FindObjectsOfType<T> iterations with fast O(1) dictionary lookups from Il2Cpp.NetworkMap.instance in HarmonyPatches.cs, GameHooks.cs, and LuaServerModule.cs.
🎯 Why: FindObjectsOfType<T> was being invoked repeatedly in hot paths like world syncing and UI event hooks, which caused massive O(N) performance overhead and GC pressure.
📊 Impact: Eliminates N full-scene hierarchy traversals on every iteration of the sync loops or scripting calls, drastically reducing CPU time and stutter during scene loads and saves.
🔬 Measurement: Monitor profiling in HarmonyPatches.cs and LuaServerModule.cs and observe eliminated CPU spikes. Also ensure dotnet test remains green.

Replaced slow `UnityEngine.Object.FindObjectsOfType<T>` iterations with fast O(1) dictionary lookups from `Il2Cpp.NetworkMap.instance` in `HarmonyPatches.cs`, `GameHooks.cs`, and `LuaServerModule.cs`.

`FindObjectsOfType<T>` was being invoked repeatedly in hot paths like world syncing and UI event hooks, which caused massive O(N) performance overhead and GC pressure.
This eliminates N full-scene hierarchy traversals on every iteration of the sync loops or scripting calls, drastically reducing CPU time and stutter during scene loads and saves.

Superseded by #285 (newer iteration of the same bot-generated NetworkMap optimization; closing duplicates). GitHub is a mirror — active development happens on Forgejo/Gitea.
