fix: 修复主题偶发渲染错误与闪烁

1. CSS 主题预加载: 浅色变量同时应用到 html.theme-preload,避免首帧读取到暗色变量导致的错色与闪烁
2. transition:
	- 移除会引起首帧抖动的相关transition:侧边栏的 width/transform 和 .content 的 transition
	- 新增作用域类 .with-anim,仅在交互(点击折叠按钮)时启用侧边栏transition,首屏不加载动画
3. 页面与分类卡片动画:
	- 移除 .page.active 的位移动画,保留透明度过渡
	- 移除 .category 的进入动画(opacity:0 + fadeIn),避免分类卡片在切页时产生浮动效果

脚本调整: 在 toggleSidebarCollapse 时添加 documentElement.with-anim,使布局过渡仅在用户交互时生效

Fixes #17
