feat: 新增免费演出雷达工具与定投评估功能，优化周报提醒逻辑

1. 新增免费演出雷达工具：含秀动/猫眼/大麦平台抓取、本地代理鉴权配置
2. 新增建行定投评估模块：四大指数PE-TTM估值与定投档位建议
3. 新增推送告警白名单过滤功能，限制推送指定指数告警
4. 重构周报首页提醒逻辑，移至服务端处理并减少前端请求
5. 新增多套调试探针脚本与单元测试用例

+// ============================================================
+// 免费演出雷达 · 本地抓取代理（零依赖单文件 · v2 常驻浏览器版）
+//
+// 用途：大麦对服务器 IP（尤其阿里云 ECS）风控极严，
+//       本代理在家里电脑运行，用家庭宽带 IP 抓大麦，
+//       工具箱页面（127.0.0.1 探测）自动把大麦请求路由到这里。
+//
+// 用法：node free_show_local_agent.js [端口，默认 8978] [--headless] [--cdp <端口，默认 9222>]
+// 依赖：仅 Node 内置模块 + 本机已安装的 Chrome 或 Edge（无需 npm install）
+//
+// v2 工作方式（解决 headless 被大麦风控识别的问题）：
+//   ① 启动代理 → 自动唤起一个【可视化】原生 Edge 窗口（默认不 headless），
+//      使用持久化用户配置目录（Cookie / 登录态 / 过验证状态落盘保存）；
+//   ② 首次使用请人工在该窗口完成滑块验证 / 登录（只需一次，会话自动保存）；
+//   ③ 代理通过 CDP（remote-debugging-port）复用【同一个浏览器实例】执行抓取，
+//      每次任务只开/关标签页，绝不新建空白浏览器环境、不重启浏览器进程；
+//   ④ 抓取前等待异步列表渲染完成；若检测到滑块弹窗，保留标签页并明确提示
+//      「需要人工完成滑块验证」，由你在可见窗口处理后重试。
+//
+// 反自动化特征参数（内置）：
+//   --disable-blink-features=AutomationControlled
