ZXCLI 0bfb926892 完成官方管线全量逆向与 demo3 v5 复刻,清理仓库
- 逆向:Ghidra/IDA 全量反编译 CoreSDKLib.dll/ThermalSDK.dll/libthermalSDK.so/
  libcoresdk.so(ARM64)/libmagcore.so,导出 analysis/ida/export/
- 解码官方渲染管线:DDT 校准表加载->快门端点选择->Q12 插值->ref(4x type1 帧
  均值)->NUC 查表->盲元补偿->窗口->LUT1024 重建->2x 升采样->调色板
- 逐像素验证:NUC+盲元 0/19200、插值 0 误差、2x 0/76800、窗口一致
- demo3 v5:完整复刻官方管线(含 DDT 解析、FFC 状态机、快门温度驱动),
  修复 load_ddt 表错位导致的零像素问题
- 鬼影根因分析写入 analysis/reverse_20260813_full.md
- 心跳/恢复机制:analysis/session_state.md + tools/resume_rev.ps1
- 新增 tsdk_pair3 增强采集工具;历史工具归档 csdk/tools/legacy/;
  根目录抓帧残留删除,历史文档归档 analysis/history/
- csdk/README.md 完整使用文档;.gitignore/.gitattributes 补 LFS 规则

/* Read the LIVE official palette: after ThermalSDK Start(), the channel
* device object holds the 256-entry palette at dev+0xb00 (4 bytes each,
* BGR order). We find the device pointer via MAG_GetOutputBMPdata which
* returns the grayscale buffer at dev+0xaf0 - the palette is 0x10 before it.
