v2.9.1 - fix: resolve build size bloat, relax compiler check & remove UPX conflict

- Re-enable anti-bloat mechanism to prevent bloated builds with Pandas and other libraries
- Restrict UPX compression to eliminate packing warnings and conflicts in Nuitka single-file mode
- Remove strict MSVC fallback logic to prevent build failures on systems without Visual Studio
- Relax compiler rules to let Nuitka automatically select and download suitable toolchains
- Switch default packaging strategy to Lite Mode with bytecode and link-time optimizations enabled

+
+### 修复
+- 修复使用 Nuitka 单文件打包时调用 UPX 产生的压缩失败警告与报错问题，恢复 UPX 仅对 PyInstaller 启用的安全策略
+- 修复 Nuitka 防膨胀插件未生效导致打包 Pandas 等第三方库时依赖扩散、生成文件体积异常暴增的问题
+- 修复未安装 Visual Studio 时因编译器判断失误强行指定 MSVC 导致的构建中断问题
+
+### 优化
+- 放开 C 编译器选择限制，无本地 MSVC 环境时交由 Nuitka 自动匹配并下载适用的轻量编译工具链（如 Zig），大幅降低打包失败率并避免文件锁死
+- 将默认打包策略调整为精简模式，默认开启字节码与链接优化，并自动剔除测试与调试等冗余模块，显著缩减最终文件体积

+## [2.9.1] - 2026-09-17
+
+### Fixed
+- Fixed compression failure warnings and errors when invoking UPX during Nuitka standalone builds; restored policy ensuring UPX only applies to PyInstaller
+- Fixed abnormal binary size bloat when packaging third-party libraries like Pandas caused by disabled anti-bloat mechanisms
+- Fixed build failures on systems without Visual Studio caused by incorrect compiler fallback logic enforcing MSVC
+
+### Improved
+- Relaxed C compiler restrictions to let Nuitka automatically match and download appropriate lightweight toolchains (such as Zig) when local MSVC is missing, reducing build failures and file lock issues
+- Set Lite Mode as the default packaging strategy, enabling bytecode and link-time optimizations while excluding redundant test and debug modules to significantly reduce output size
