perf: X3dPart 布尔结果改为按需重建，开图不再逐件建体
方案 A（见 AcDbX3dSolid-refactor-plan.md 第 13 节）。开图慢的瓶颈是 AecDbX3dPartEntity::dwgInFields 无条件调 m_pPart->Create()，每个 part 都要 N 次建体 + N 次布尔。 A1：引入 m_bDirty - AecDbX3dPart 增加 m_bDirty，构造/拷贝构造置 true - 15 个改参数的接口置脏：AddX3dSolid、RemoveAt、RemoveAll3dSolidRec、 SetOrgPoint、SetAxis、SetBoolOperFor、SetHide、SetActive、PeelOffTheSkin、 AddMove×2、ResetMove、AddRotate、ResetRotate、CopyFrom - 新增 Rebuild()（protected）：清标志后无条件重建，原 Create() 的函数体 - 新增 EnsureCreated()：m_bDirty 或 m_pSolid 为空时才 Rebuild Create() 保持「显式调用一律重建」的语义，内部转调 Rebuild()。原因是外部 有 10 处先取 GetX3dSolid(0) 直接改（如 AecDbBDPipeBase:941 调 TransformBy） 再调 Create()，部件感知不到这类改动，做成幂等会漏掉重建。 A2：开图不建几何 - AecDbX3dPartEntity::dwgInFields 去掉 m_pPart->Create()，由 AecDbX3dPart::dwgInFields 结尾置脏 - 读入口统一先 EnsureCreated：CreateDraw3dSolid、Draw3d、getOsnapPoints、 GetForHouseSubtract 收益：关闭/冻结图层、视口外、XREF/审核/发布等不绘制的场景完全省掉建体与 布尔；全图可见时开图时间下降、首次 regen 补回。
