feat: Phase 3 Web — 业务 API(stocks/factors/backtests)+ Next.js 前端
- 后端业务 API:GET /api/stocks(搜索/分页)、GET /api/factors(因子目录)、POST /api/factor-tests 与 /api/backtests(Research Spec 驱动同步执行)、GET /api/backtests/last;Annotated 依赖注入 + CORS(dev) - Repository 批量查询 get_range_many(研究装配一次查询,避免逐只拉取) - 前端 frontend/web:Next.js 15(TS) + ECharts —— 总览 / 股票池 / 因子研究(IC·RankIC·分层展示) / 回测(净值·回撤·月度·持仓·未建模标注) - 前端只消费业务 API 与标准化 BacktestResult,无 Qlib/SQL 概念泄漏 - 真实数据:同步 20 只权重股 2023-2024 日线(9680 根)支撑截面研究 - 验证:API 集成测试 8 项(DTO 校验/装配/引擎/标准结果,内存 repo 全链路)+ 全量 pytest 68 passed;前端 tsc + next build 通过;无头浏览器端到端(factors/backtest 页面渲染后端数据) - ruff clean
