Conflict resolution summary:
- .gitignore: kept dedicated-server-specific ignore entries (tmp*/, _server_asset_probe/, server-data/) and also kept main-side entries (*.user, /out).
- Minecraft.Client/Common/Network/GameNetworkManager.cpp: kept int64_t seed from main and preserved dedicatedNoLocalHostPlayer logic from dedicated-server.
- Minecraft.Client/Windows64/Network/WinsockNetLayer.cpp: preserved dedicated-server shutdown flow and also included main-side cleanup for s_smallIdToSocketLock.
- Introduced `ServerMain.cpp` for the dedicated server logic, handling command-line arguments, server initialization, and network management.
- Created `postbuild_server.ps1` script for post-build tasks, including copying necessary resources and DLLs for the dedicated server.
- Added `CopyServerAssets.cmake` to manage the copying of server assets during the build process, ensuring required files are available for the dedicated server.
- Defined project filters in `Minecraft.Server.vcxproj.filters` for better organization of server-related files.
