MacDesk v1.3.0

新功能 / Features

• 文件夹堆叠 Folder Stacks（#2）：叠放模式下右键桌面文件夹选 "以堆叠方式展示" —— 图标带向下角标，单击原地展开内容为真实图标（可打开 / 拖出 / 右键 / 空格预览），再点收起。拖文件到文件夹上仍是移入；把展开的子项拖到空白处即移出到桌面；拖拽悬停半秒原地弹开；超出屏幕容量显示"还有 N 项"。分组就是文件夹本身——跨机迁移、卸载 MacDesk 都不丢。
  In Stacks mode, right-click a desktop folder and pick Display as Stack: the icon gets a chevron badge, a single click expands the folder's contents in place as real icons (open / drag out / right-click / Space preview), click again to collapse. Dropping files on the folder still moves them in; dragging an expanded item to empty desktop moves it out; hovering a drag over the folder springs it open; overflow shows an "N More" tile. The group IS the folder — it survives machine migrations and even uninstalling MacDesk.
• 桌面图标开关 Desktop icon toggles（方向来自 direction by @climashscape, PR #3）：设置 → 通用可显示/隐藏 此电脑、用户文件、网络、控制面板、回收站；首次启动跟随原生桌面当前的选择。
  Show or hide This PC, User's Files, Network, Control Panel and the Recycle Bin from Settings → General; the first run follows your native desktop's current choices.
• 右键菜单补全"重命名" Rename in context menus（思路来自 idea by @climashscape, PR #5）：原生 shell 文件菜单此前一直缺"重命名"动词，现在出现在"删除"之后，走 MacDesk 的内联重命名框。
  The native shell file menu never offered Rename; it now appears right after Delete and opens MacDesk's inline rename box.

修复 / Fixes

• 壁纸亮部烧白（#1）：壁纸预解码到屏幕尺寸，绕开个别核显驱动（如 Intel UHD 630)的硬件合成缺陷；另加"软件渲染"保底开关（设置 → 通用，重启生效）。
  Wallpaper highlights burning out on some iGPUs (#1, e.g. Intel UHD 630): the wallpaper mirror is now pre-scaled to screen size, bypassing the driver's hardware-compositing defect; a Software Rendering fallback toggle was added under Settings → General.
• 更新器识别预发布版本；--soft 启动不再影响自启参数；安装器在覆盖安装前强制清理滞留的辅助进程。
  The updater is prerelease-aware; --soft no longer taints autostart args; the installer force-cleans lingering helper processes before overwriting files.
