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
