Day3 教学示例：增强版计算器接入 + QMainWindow/QSS 两版参考实现
- calculator_designer_ext（Day2 增强版：表达式求值 + 括号，递归下降解析器）接入 cmake - calculator_mainwindow（Day3 上午）：增强版计算器装进 QMainWindow， 菜单/状态栏/历史停靠窗，纯代码 + 显式 connect，与 mainwindow_showcase 形成坑卡对照 - calculator_mainwindow_qss（Day3 下午）：上午版 + QSS 双主题美化（按键分色/伪状态/深浅切换） - 验证 mainwindow_showcase（QMainWindow 六大组件综合演示，.ui + .qrc） - OUTLINE_4DAY.md / ASSIGNMENTS.md Day3 衔接增强版起点 + 参考实现指引 - 补提交 Day2 calculator/ 与 calculator_designer/ 参考实现（CMakeLists 已引用） - 全量构建 28/28，4 目标离屏自测退出码 0 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
