一次开图要做 5641 次截面恢复（22.4 s），其中大量内容重复，
而每次恢复都是"写临时 SAT 文件 + 从盘 acisIn + 删文件"，单次 2.7~5.5 ms，
还要过一次杀软。本提交加一级母体缓存，命中直接 clone 返回。
新增 CoreLibrary/SectionRegionCache.{h,cpp}，三个通道按 key 的正确性强度分开：
- kParam：纯参数 hash，用于 AecDbEwFitting::GetSection 的两个重载
（key = dD/dt/HLR 标志 或 W/H/dt/HLR 标志，同参数必同几何）
- kAttr：类名 + spec XData（排除编号，并跳过 Id/点/向量/矩阵/二进制类型），
只给 AecDbEwPipe 用。AecDbEwPipeBase 是很多类的基类，其余派生类实例间的
区别就是截面，不满足"同数据必同截面"，所以一律走内容 hash
- kText：SAT 文本内容 hash，用于 RegionAcisInDwgInFields 的其它类
与 CoreTools::StringToRegion 的两个重载
约定：母体由缓存持有、永不外泄，Acquire/Put 都返回 clone，调用方拥有返回值；
母体不入库；每条通道 4096 条上限（AEC_SECTION_CACHE_MAX 可调），超出按 FIFO 淘汰；
AEC_SECTION_CACHE=0 可整体关闭做 A/B；卸载时 ClearAll() 释放，避免 DLL 析构顺序问题。
关键发现：SAT 文本第 2 行带存盘时间戳
16 Autodesk AutoCAD 19 ASM 219.0.0.5600 NT 24 Thu Oct 22 10:19:20 2026
同一几何存盘时间不同，整份文本就不同（采样里两份 2596 字节的文本只差
10:19:20 与 10:19:16），这正是内容 hash 命中率只有 54% 的原因，与截面无关。
因此新增 HashSatText()：算 hash 时跳过第 2 行，仅当该行含 "Autodesk" 时才跳过。
计数器也改用同一口径，避免两套统计互相矛盾。
实测（big1.dwg / AutoCAD 2020 / R230 Debug，AEC_SECTION_CACHE 关 vs 开）：
开图墙钟 108~113 s -> 98 s
截面恢复总耗时 22.4 s -> 9.87 s（-56%）
StringToRegion 14.05 s -> 7.73 s
RegionAcisIn 8.38 s -> 2.14 s
临时文件 6773 次/9.34MB -> 2875 次/3.61MB
命中率 text 65.5% / attr 84.1% / param 88.8%
clone 开销 命中 58us、未命中 73us（合计 0.37 s，可忽略）
顺带：
- tools/run_acad_perf.ps1 增加 -CacheOff 开关，用于同一构建上的 A/B 对比
- SectionPerfCounter 增加 AppendReport()，让缓存统计也写进同一份报告文件
- 诊断口子 AEC_SAT_SAMPLE=n 可导出未命中的 SAT 原文，用于定位这类差异
验证：R230 Debug 编译通过并部署；用脚本自动开图各跑一次（缓存关/开），
数据已写入 pipe-section-region-performance-plan.md。
尚未做：R190 编译（本机缺 v100 工具集）、Release 构建的收益复测、
开图期间 1140 次 RegionAcisout 回写（与本缓存无关，需单独立项）。
