fix: 修复首页卡片字数与 Hero 滚动，移除光感跟随 (v1.1.6)

修复
- 首页文章卡片开启"显示字数"后无效果：该配置项此前只有声明没有实现，现已在文章流卡片接入服务端字数统计（依赖 API 扩展包，未安装时自动隐藏）
- Hero 下滑箭头滚动不到位：Hero 为固定背景（position: fixed），此前箭头额外减去了导航栏高度，导致内容区上方始终露出一段 Hero 渐变；现与滚动吸附逻辑对齐，内容区顶部直接对齐视口顶部
- 鼠标点击特效开启后无效果：特效类型默认值为 off（关闭），开启开关但不选择类型时静默不生效；默认值改为"社会主义核心价值观"

移除
- 移除鼠标光感跟随功能及对应配置项

优化
- 上下篇导航：新增方向箭头与悬停反馈（背景、位移、变色），移动端收紧内边距
- Hero 一言自动刷新改为淡出→换文案→淡入的过渡动画，避免生硬跳变
- README 全面更新：环境要求、插件适配表（新增微信读书与 API 扩展包）、自定义页面模板、功能说明、目录结构与开发注意事项
