+================================================================================
+【物品放置方块】(placeblock) 服务 —— 创造栏显示 2D 物品图标, 放置出指定方块模型
+================================================================================
+背景: 网易 1.10 自定义物品不支持 minecraft:block_placer(实测"放不下去");
+      原版 1.21.60 物品虽能 block_placer, 但其 menu_category 只能进原版分页,
+      进不了网易自定义分页(如 xy_finished)。两者无法兼得。
+方案A(脚本补位): 方块本体 register_to_creative_menu:false 不出现在创造栏;
+      另建带 2D 图标、category 指向自定义分页的网易 1.10 物品(分页正确);
+      手持该物品右键任意方块 -> 在被点面的相邻格放置对应方块, 消耗 1 个
+      (创造模式不消耗)。
+
+路由: 走 FeatureDispatcher 的 itemUseOn(itemName -> 服务), 与其它转换服务同机制。
