fix: 修复部分平仓盈利计算错误
问题:部分平仓时,历史记录显示的是全仓位盈利,而非实际平仓部分的盈利 根本原因: - AnalyzePerformance 使用开仓总数量计算部分平仓的盈利 - 应该使用 action.Quantity(实际平仓数量)而非 openPos["quantity"](总数量) 修复: - 添加 actualQuantity 变量区分完整平仓和部分平仓 - partial_close 使用 action.Quantity - 所有相关计算(PnL、PositionValue、MarginUsed)都使用 actualQuantity 影响范围:logger/decision_logger.go:428-465 Co-Authored-By: tinkle-community <tinklefund@gmail.com>
