自动退出登录卡死：_performLogoutAndExit 只 pop() 一层，而解锁/收藏品页是 push
在 HomePage 之上的，退登后被弹回「风险」hub，同时 _loggingOut 仍为 true，
PopScope(canPop:false) + 返回键转圈形成死局。改为 popUntil(isFirst)。
旅行伙伴发不了：它是 ItemKind.Character = 9，与搭档 Partner = 10 是两种东西，
原先收藏品的类型列表 [1,2,3,10,11,12] 里根本没有 9。按客户端实现，角色不走
userItemList(ExportUserItems 不导出 itemKind 9)，而是
upsertUserAll.userCharacterList 的 {characterId, level, awakening, useCount}，
配 isNewCharacterList 一行一字符。新增发放与 5 槽 charaSlot 编组页，
含「把槽 0 复制到其他槽位」，并校验所选角色确为已拥有或本次待发放。
宽屏布局：各页只有 ConstrainedBox 限宽、没有居中容器，1440 窗口下内容贴左、
右侧大片空白。抽出 responsiveBody 统一居中；B50 预览改用按宽度适配
(InteractiveViewer constrained:false + FittedBox fitWidth)，横屏下不再被
contain 缩成中间一小块，导出仍是原始 1762x1850。
CI：.github/workflows/build.yml 先跑 analyze+test 作为门槛，再产出
Windows exe、Android apk、iOS 未签名 ipa(macOS runner，无证书故不可安装)。
README 从 Flutter 模板改写为实际文档，含 path_provider/jni 与 JBR jlink
两个构建环境坑的说明。
