perf(miniprogram): 全面性能优化 — 分包加载 + 请求缓存 + 渲染优化
分包加载(主包从 517KB 降至 275KB,-47%): - 将 27 个页面拆入 6 个分包(health/doctor/mall/profile/content/device) - vendors.js 从 192KB 降至 36KB(-81%) - echarts 514KB 仅在访问健康趋势页时按需加载 请求层优化: - GET 请求增加 in-flight 去重 + 60s TTL 响应缓存 - 新建 points store 集中管理积分/签到状态(消除 5 处重复调用) - health store todaySummary 增加 60s TTL - mutation 后自动失效缓存(health input/daily-monitoring) - logout 时清空请求缓存 渲染优化: - 7 个组件添加 React.memo(EcCanvas/TrendChart/Loading/EmptyState 等) - 修复 TrendChart setChartReady 导致的双重渲染 - 静态数组(quickServices/quickActions/trendLinks)提取到模块级 - restoreAuth 从页面级提升到 App 级别 - 文章列表图片添加 lazyLoad 构建优化: - prod 配置添加 terser(drop_console + drop_debugger) - crypto-js 从全量引入改为按需引入(AES + Utf8)
