George BerkshireandMavis c04acf0ab6 feat: quant_engine 独立量化引擎(v1.2.0 重构 bootstrap)
从 research_results 抽出纯回测核心能力,形成独立成员仓。

## 模块(10 个核心)

| 模块 | 内容 |
|---|---|
| alpha_factors | 158 alpha 公式 + 24 基础算子(移植自 qlib alpha158)+ JSONB 工具 |
| execution | 执行仿真(成本/滑点/T+1/涨跌停/部分成交/价差)+ 多日 NAV + PnL 拆解 |
| indicators | 50+ 技术指标(MACD/KDJ/布林/ATR/ADX/等) |
| data_adapter | 桥接 qtdb_pro 长表与新模块(rename/long-wide/复权/vwap 代理) |
| backtest | weight-based 多日仿真 |
| metrics / perf_stats | 绩效指标 |
| factor_library | 通用方法(turnover/IC/winsorize/OLS) |
| portfolio_decomp / risk | 组合分解 + 风险指标 |
| logging | 统一 logger(标准库 + 可选 loguru) |

## 设计原则

- 零重型依赖(numpy/pandas/scipy)
- mypy strict 0 errors(12 source files)
- 394 tests passed(从 research_results 复制 + 适配)
- ruff clean

## 与 research_results 的关系

- research_results 通过 re-export wrapper 保持向后兼容(src.shared.X → quant_engine.X)
- 47 proj 的 import 路径暂时不变,后续逐步迁移
- 本仓角色:researchhub_workspace 引擎层
