- 后端改为 config/app.json；pytest 使用 config/app.test.json 与 set_config_file，不再依赖环境变量；移除 pydantic-settings。 - 前端 API/WebSocket 由 config/webui.json 经 Vite define 注入。 - 代理分数按延迟与随机取用次数计算，新增 use_count 与 proxy_scoring；保存设置时同步调度器启停。 - 仪表盘双饼图（可用/待验证协议）；设置页去掉调度器启停按钮并移动立即验证；爬取全部结束后自动提交全量验证。 - 删除 script/settings_maintain.py（此前已标记删除）。 Made-with: Cursor
