### 开图期回写的修复：把 clone 延迟到 ToJson()
按上面的结论，`m_pipes` 的唯一用途是 `ToJson()` 导出 `__pipes__`，
而截面参数（`KEY_SECSHAPE` / `KEY_SIZE1` / `KEY_SIZE2` / `PIPE_THICK` / `KEY_SECCEN`）
在建截面时已经写进 spec XData，**完全可以按参数重建**。
所以绘制期不必保留几何，等导出时再建。
改动：
1. `AecDbEwPipeBase` 新增两个方法
- `BuildSectionFromXData()`：按 XData 参数重建截面（圆形 / 矩形），自定义截面返回 NULL
- `CloneParamsOnly()`：生成只带参数（XData / 放样线 / 实体属性 / GUID / Breaks）、
**不含截面几何**的副本
2. `AecDbEwPipeBase::ToJson()`：`GetSection()` 为空时回退到 `BuildSectionFromXData()`，
保证 `__section__` / `__section2__` 仍在
3. 把所有 `m_pipes.push_back((AecDbEwPipeBase*)pipe.clone())` 改成
`m_pipes.push_back(pipe.CloneParamsOnly())`，共 **30 处 / 6 个文件**：
ClimbStair(10)、ZLineStair(6)、BossHolder(4)、MRPLineStair(4)、Hanger(3)、Holder(3)
先只改楼梯两处时，回写从 1140 降到 960 —— 用 `AEC_WRITEBACK_TRACE` 再抓栈，
解析出剩余 960 全部来自 `AecDbClimbStair::DrawLadderH3d`（爬梯），
恰好对应 ClimbStair 的 10 处，于是把其余 20 处一并改掉。
实测（big1.dwg，AutoCAD 2020 / R230 Debug）：
| 指标 | 初始 | 加缓存后 | 本次修复后 |
| --- | ---: | ---: | ---: |
| 开图墙钟 | 108~113 s | 98 s | **93 s** |
| 开图期回写 | 1140 次 / 2.38 s | 1140 次 | **0** |
| `EwPipe::RegionAcisIn` | 3082 次 | 3082 次 | **1942 次** |
| 临时文件 | 6773 次 / 9.34 MB | 2694 次 / 3.34 MB | **1733 次 / 2.34 MB** |
| 截面恢复总耗时 | 22.4 s | 9.87 s | **9.4 s** |
**待验证（本次没条件跑）**：JSON 导出。`m_pipes` 里现在是"无几何的参数副本"，
`ToJson()` 靠 `BuildSectionFromXData()` 重建，需要实际触发一次导出，
确认 `__pipes__` 里每条仍有 `__section__` / `__section2__` 且数值与改动前一致。
### Phase 2：临时目录治理（可选，止血）
Phase 1 之后残余落盘只剩"每个唯一截面一次"，收益小；但如果现场仍被杀软拖慢，可做这一步：
