详细描述

三体点质量引力偏导数（梯度）函数块

继承 BlockThirdBodyPointMass，在其基础上增加三体点质量引力梯度计算。重写 run()：调用基类加速度计算，同时计算梯度张量，将 ∂a_3body/∂r 累加到 A 矩阵的 bottom-left 3×3 位置。

三体点质量引力加速度： a = GM₃ · [ (r₃ - r) / |r₃ - r|³ - r₃ / |r₃|³ ]

梯度（对航天器位置 r 的偏导数）：间接项梯度 = 0（与 r 无关）直接项梯度 ∂a_direct/∂r = -GM₃/|d|³ · I + 3·GM₃/|d|⁵ · (d ⊗ d) 其中 d = r₃ - r，该形式与 aPointMassField 的 Hessian 完全相同

A 矩阵布局（6×6，行优先）： ┌ ┐ │ 0 I │ rows 0-2: 位置运动学 │ ∂a/∂r 0 │ rows 3-5: 加速度偏导数 └ ┘ ↑ 本块写入 ∂a/∂r (rows 3-5, cols 0-2) 三体引力与速度无关，∂a/∂v = 0

输入端口（继承）：

"Pos"：位置向量（3维，继承自 BlockThirdBodyPointMass）

输出端口（继承 + 新增）：

"AccThirdBody"：三体引力加速度（3维，继承自 BlockThirdBodyPointMass）
"AMatrix"：动力学雅可比矩阵 A(t)（36维，新增，本块累加 ∂a/∂r 分量）

导数端口（继承）：

"Vel"：速度导数（3维），累加三体引力加速度

注解: 可替换 BlockThirdBodyPointMass 使用，提供梯度计算的同时保持原有加速度输出
