Yueyue Structure Block Fixes

Yueyue Structure Block Fixes

Preserves structure-block templates' saved waterlogged states instead of automatically filling originally dry stairs, slabs, signs or fences from nearby/target water. Existing wet states stay wet; later normal fluid updates still apply. Only structure-block loading is changed, not natural structures or every template caller.

With Fabric Carpet installed, corner detection follows max(80, structureBlockLimit + 1), including the extra boundary corner. Waterlogging preservation works without Carpet. Install on the logical server: local client installation covers singleplayer; a remote server needs it server-side. This file targets Minecraft 26.3.

中文：结构方块加载时保留文件记录的干湿状态，修复原本不含水的方块被错误灌水。安装Carpet后角落检测跟随structureBlockLimit规则，无Carpet时含水修复仍有效。应安装在实际运行世界的服务端；26.3文件不能用于其它版本。

Runtime and dependencies

• Minecraft 26.3 / Java 25 / Fabric.
• Client: Install for singleplayer; optional on remote clients
