GEO Tool — 跨平台打包构建脚本

用法:
    python build_scripts/build.py            # 打包 Python 可执行文件
    python build_scripts/build.py --clean    # 先清理旧构建再打包
    python build_scripts/build.py tauri      # 打包 Python 可执行文件 + 构建 Tauri 桌面应用

输出:
    dist_python/geo_tool_app          (macOS / Linux)
    dist_python/geo_tool_app.exe      (Windows)
    src-tauri/target/release/GEO工具    (Tauri 桌面应用)
