feat(ui): 开机自启动 + 窗口大小记忆

- win32/autostart: SetAutoStart/IsAutoStartEnabled 操作 HKCU Run 键 - win32/window_size: GetWindowSize 通过 GetWindowRect 获取窗口尺寸 - config: 新增 AutoStart、WindowWidth、WindowHeight 字段 - store: Preferences/SetPreferences 扩展支持 autoStart + windowSize - dialog_preferences: 新增"开机自启动"复选框 - app.go: 启动时恢复窗口大小，关闭时通过 SetWindowSize 保存 - i18n: label_auto_start / hint_auto_start 三语翻译
