Flow 0.4.10 · Small uninstaller and tray fixes

安装器和卸载器独立编译。安装器携带主程序并识别旧安装目录，卸载器仅约 447 KiB，不包含下载引擎和播放器；卸载保留下载文件、个人配置和播放器环境。托盘右键打开“显示主界面 / 停止下载并退出”菜单，左键单击不动作，左键双击显示主界面。修复英文模式下分类按钮、退出按钮等漏译。中英文 README 已更新。

Installer and uninstaller are independently compiled. The installer bundles Flow and detects the previous installation directory. The small native uninstaller is about 447 KiB and excludes the download engine and player; uninstall keeps downloads, settings and player runtime. Right-click opens the tray menu, a single left-click does nothing, and a left double-click restores the main window. Fixed untranslated category and exit buttons in English mode. Bilingual README updated.

Validation: 55 tests passed across the app, installer and uninstaller; 2 optional player tests ignored. Packaged backend self-check, embedded payloads, uninstall file preservation, signed update manifest and asset SHA-256 verified.

Downloads: Flow-Setup-0.4.10-x64.exe is the installer; Flow-0.4.10-windows-x64-portable.zip is the portable package. Exit Flow completely from the tray before upgrading. Rerun the installer to replace the old full-size uninstaller; in-app updates replace the main program only.
