mypy (13 errors → 0): - portfolio/optimizer: register_optimizer 返回类型改为 Callable 装饰器签名 (原标注 type[WeightOptimizer] 导致 4 个子类 Too many arguments) - factor/engine: _datetime_to_int 用 isinstance 收窄替代 object→int 强转 - factor/analysis: 删多余 type:ignore（改由 mypy override 统一处理 scipy） - backtest/orders, execution: np.sqrt 表达式用 float() 包裹消除 no-any-return - MyTT.pyi: MACD 签名删除错误的 LOW/HIGH 参数（与 MyTT.py 实际签名对齐） - pyproject: 新增 scipy mypy override (ignore_missing_imports) ruff format: 8 个 test 文件格式化 验证: 564 passed, mypy 192 文件零错误, ruff check/format 全绿
