v1.1: 修复 Windows 跨平台兼容性 & 按钮高对比度配色

【跨平台修复】
- cmakegenerator.cpp: CMAKE_C_COMPILER / CMAKE_MAKE_PROGRAM 提前到 project() 之前设置，避免 CMake 在 Windows 回退 NMake
- cmakegenerator.cpp: MinGW 编译器路径下自动推导 mingw32-make.exe
- mainwindow.cpp: generateCMake() 在 Windows 下添加 -G 'MinGW Makefiles'
- mainwindow.cpp: compileProject() cmake 添加生成器参数 & mingw32-make 替代 make

【UI 改进】
- 全部操作按钮升级为 Material Design 高对比度配色（Darker 系列）
- 按钮添加圆角和内边距，提升可读性和视觉层次

【工程规范】
- 新增 .gitignore，排除编译产物 (.o / moc_*.cpp / Makefile / 二进制)
- README.md 重写，补充 Windows 编译指南和技术要点
- 需求规格说明书更新至 v1.1
