学生主要用 Windows，Docker 方案不再需要：删掉 tools/docker/ 及 README/HANDOFF/ CMakeLists 里的相关引用（含一处已失效的 docker_run.sh 死链接）。 install_qt_host.sh 现在同时装期号匹配的 Qt Creator 4.11.0：官方 .run 安装器 强制要求 Qt 账号登录且无 Skip 选项，改用 tools/extract_qtcreator_payload.py 直接从 .run 里定位、解出内嵌的 7z payload，绕开账号登录。提取逻辑先解到 staging 目录再原子替换到位，避免中途失败留下部分安装但被判定为"已装"； 候选 7z 复用同一临时文件，不会在磁盘上堆多份安装包大小的临时拷贝。

"""Extract the Qt Creator payload from a QtIFW .run installer without running
|
|
its GUI. The official .run for Qt Creator (this vintage) hard-gates the wizard
|
|
behind a mandatory Qt account login with no Skip option, so the GUI/script
|
|
automation route is a dead end. The installer binary is a self-extracting
|
|
QtIFW archive: an ELF stub with one or more embedded 7z streams appended.
|
|
The real payload (bin/, lib/, share/, libexec/) lives in one of those streams;
|
|
this scans for the 7z magic, tries each occurrence, and keeps the one whose
|
|
contents include bin/qtcreator.
|
|
|
|
Usage: extract_qtcreator_payload.py <installer.run> <dest_dir>
