+      根因: ci-sanitize 继承 conan-release，后者 CMAKE_C_COMPILER/CXX=cl (MSVC)，
+      但 -fsanitize=address,undefined 是 clang/GCC flag，CI 运行在 ubuntu-24.04+clang-18，
+      编译器覆盖冲突导致 sanitizer 行为不可预测。
+      修复: ci-sanitize 改为独立 preset (generator Ninja + toolchainFile
+      ${sourceDir}/build/Release/conan_toolchain.cmake + CMAKE_C_COMPILER=clang-18
+      + CMAKE_CXX_COMPILER=clang++-18 + flags -fsanitize=address,undefined
+      -fno-omit-frame-pointer)。新增 ci-threadsan (TSan)。
+      验证: cmake --list-presets 4 个全部解析通过，Release 构建 cmake --build build --config Release
