- 统一侧边标签渲染与点击的固定父标签视口计算 - 展开或收拢章节后保持当前章节可见，避免侧边栏滚动锁死 - 侧边栏跳转保留滚动与折叠状态，不再因点击章节而上下滑动 - 修复固定父标签占用行时最后一个标签无法显示的问题
- 首行滚到章节标题时沿用上一行所属大章 - 子节进入首行后才切换顶部大章 - 避免滚轮滚动一格造成两次内容跳变
- 左键点击大章时切换展开收起状态 - 同时打开该章的index内容 - 更新侧边栏tooltip交互提示
- 移除水平排列时按可用宽度等比缩小子组件的逻辑 - 子组件保持自然尺寸，一行放不下时自动换行绘制 - 高度计算与鼠标命中测试同步适配换行布局
- 内容区滚轮滚动手持加速键时以 3 倍速度滚动 - 侧边栏标签 tooltip 新增滚动加速操作提示 - 折叠提示文本应用灰色弱化样式
- 在 Tooltip 中保留 ItemStack，使物品 tooltip 走带物品栈的渲染重载 - 由 RenderTooltipEvent 统一注入 W 键提示，移除配方和方块组件重复的手动提示 - 保留 W 键跳转所需的 hoveredDocLink 记录
- 悬停投影结构按钮时显示双行快捷键提示 - 为MDRenderContext增加多行tooltip支持 - 补充中英文案并重新生成英文语言文件

本次拉取请求对指南UI、工具提示处理以及水平行布局渲染进行了多项改进。其中最重要的改动包括：增强在指南间导航时UI状态的保持能力，重构工具提示数据结构以更好地支持物品工具提示，以及重新设计水平行布局以支持自动换行而非缩放组件。此外，还对配方和方块渲染逻辑进行了小幅改进和清理。
指南UI改进：
openGuideOnClientPreservingLabelState并重构指南打开逻辑，使其可选择继承标签状态来实现。[1] [2] [3] [4] [5] [6]工具提示处理改进：
MDRenderContext.Tooltip记录，使其始终存储关联的ItemStack，从而支持更灵活的工具提示渲染，并更新了工具提示渲染逻辑以使用该信息。[1] [2]水平行布局重新设计：
MDRowComponent），采用自然尺寸、自动换行的算法，不再缩放组件以适配一行。这改善了当一行内容过多时的可读性和可用性。[1] [2] [3] [4]其他UI/UX改进：
MDNBTStructureComponent中，当鼠标悬停在结构按钮上时，为结构投影控制添加了快捷键工具提示。构建配置：
