feat(updater): 软件一键自动更新 + 启动检查角标

updater.py:
- ReleaseInfo/AssetInfo 结构化检查结果，取代旧 tuple
- download_update 流式分块下载(64KB chunk, 512KB进度回调)，支持重试/取消/代理
- apply_update 生成中转 bat(%TEMP%) detached 启动：等 exe 退出 →
  PowerShell Expand-Archive 解压 → robocopy 镜像覆盖(/is 强制覆盖 exe,
  /xd config debug /xf crash.log settings.json 保留用户数据) → 重启

settings_page.py:
- 检查更新发现新版本 → 弹窗[立即更新/稍后] → 流式下载带进度可取消 →
  下载完成弹[重启并安装] → apply_update + quit
- 同步按钮下载时复用为取消入口，_fmt_size 字节进度
- 源码模式(is_frozen=False)拦截: 提示 git pull && uv sync, 不下载不生成 bat
- 新增设置项「启动时自动检查软件更新」(默认开)

app.py:
- _StartupUpdateChecker 后台线程启动静默检查, 有新版本标题栏挂角标
- 退出时正确停线程
