feat(server,web,desktop,shared,deploy,docs): Linux 一键安装与 classhelper 运维命令、更新检查、图表去 echarts,版本统一 1.1.0

Linux 交付链(新增)
- deploy/install.sh:一键安装器(CLASSHELPER 大字 TUI、native/docker 双形态、向导选安装目录/
  端口/数据库/初始管理员密码);识别 apt/yum/dnf 只补缺的依赖、建独立系统用户、下载内置 Node
  运行时(glibc < 2.28 的 CentOS 7 自动改用 unofficial-builds 的 glibc-217 构建)、幂等覆盖安装
  (保留 config.env 与 data/,不重置密钥)、全程写 /var/log/classhelper/install.log;
  `--check` 只体检(不需要 root)、`--yes` 无人值守、`--package` 支持内网离线分发。
- deploy/classhelper:运维命令 —— status / doctor / password / backup(list,restore,schedule) /
  upgrade / rollback / start|stop|restart|reload / logs / config / port / key rotate / uninstall /
  completion / help。特权操作一律校验 EUID,关键动作写 /var/log/classhelper/audit.log。
- deploy/tools/admin-cli.mjs:离线账号工具(改密、列账号、VACUUM INTO 一致性快照、哈希回滚),
  直连数据库 —— 服务停机也能救急,不需要先有一个能登录的账号。
- deploy/{classhelper.service,profile.d,logrotate.d,systemd}/ 模板 + Dockerfile.linux-package。
- scripts/dist-server.mjs 增加 --platform linux(根脚本 `pnpm dist:server:linux`),产物
  classhelper-server-linux-x64-<版本>.tar.gz + 同名 .sha256;新增 GitHub Actions workflow 在
  ubuntu runner 上构建并挂 Release(@libsql/linux-* 这类平台相关依赖只能在 Linux 上装)。
- docs/linux-deploy.md:安装 / 运维命令 / 升级回滚 / 备份恢复 / 排障 / 安全清单 /
  Ubuntu 22.04 与 Rocky 9 的验收清单。deploy/install-linux.sh 改为转发壳,不留两份实现。

三处必须知道的取舍(已写进 AGENTS.md §5 第 59 条)
- 配置真身在 /etc/classhelper/config.env,安装目录里的 .env 是指向它的软链:Web 端
  「数据库管理 → 一键切换」改写的是 <安装目录>/.env,而 systemd 注入的是同一份配置 ——
  两处不是同一个文件时,切换会「看起来成功、重启后又连回旧库」。classhelper doctor 有专门断言。
- 升级/回滚替换程序文件用「改名 + 就位」而不是 rm+cp:升级时正在运行的就是 bin/classhelper
  自己,直接删掉同名文件会让 bash 读到半个脚本。
- 交叉构建(在非 Linux 机器上打 Linux 包)会在包内写 .cross-built 标记、doctor 据此提示:
  已核对 @libsql/linux-x64-gnu 与 -musl 就位且无 win32 残留,但 prisma CLI 的原生 schema engine
  是宿主平台的,Web 端「数据库一键切换」那一步存疑;正式产物一律走 CI。

更新检查(此前只在工作区,本次一并提交)
- 服务端 modules/update:由服务端转发 GitHub Releases(Web 端 CSP 不允许直连),离线/限流/超时
  一律收敛成 ok:false + 一句人话,失败结果同样进缓存;?force=1 只对管理员生效(避免刷爆匿名限流)。
- 版本比较放 @classhelper/shared(compareVersions / isNewerVersion),三端共用;服务端版本号
  改由 lib/version.ts 读 package.json,不再在 app.ts 里写字面量。
- Web 端顶栏「检查更新」弹窗、客户端「关于」页的检查更新与诊断信息。

Web 端 / 客户端
- 成绩图表改用自包含的轻量组件(ScoreBarChart / ScoreLineChart),不再全量引入 echarts
  (原先 echarts 占桌面端渲染产物 1.12MB、Web 端 1.13MB);柱状图是纯 HTML/CSS,折线图是
  viewBox SVG,均无 resize 监听。
- Element Plus 图标改为按需注册(两端各一份 icons.ts),新增 scripts/check-icons.mjs 静态门禁
  并挂进两端 build —— 漏注册的后果是界面静默渲染空白,只在控制台一条 warning。

版本号统一 1.1.0
- 5 份 package.json、deploy/package.runtime.json、.env.example 的 APP_VERSION、
  docker-compose 与两个 Dockerfile 的镜像标签、Linux 安装包名示例、README 首页版本;
- ClassIsland 插件 manifest.yml 与 BridgeService.PluginVersion 同步(verify:classisland-plugin
  有 manifest ↔ code 的一致性断言);
- 刻意保持不变的是**历史性表述与举例**:docs/mysql.md 的「自 v1.0.0 起内置 MySQL 适配器」、
  shared/utils.ts 讲版本比较用的 1.0.0 / 1.0.0-fix、README 验收表里的实测记录。

* 实现要点(决定了这里为什么不需要 resize 监听):
* - 柱高用**百分比**:`.bar-track` 是行方向 flex 里 `flex:1` 的子项,高度确定,
* 柱子的 `height: X%` 直接按它解析;
* - 刻度与网格线用**零高度 flex 行 + `justify-content: space-between`**:
* 零高度元素的中心正好落在 i/(N-1) 处,与柱状区上下边界精确对齐;
* - 纵轴刻度列与绘图区共用同一套上下留白(数值行 18px / 标签行 28px),因此永远对齐。
*
* 与桌面客户端那份(`packages/desktop-client/src/renderer/components/ScoreBarChart.vue`)
* 是刻意分开的两份:两端的设计令牌体系不同(`--ch-*` 浅/深色 vs `--el-*`),

* 全量注册既把 144KB 死代码打进主 chunk,又要在启动时执行 293 次 `app.component()`。
*
* **为什么不改成模板里逐个 import**:本项目的图标是按**字符串名**引用的
* (菜单/路由配置里的 `icon: 'Odometer'`、按钮上的 `:icon="'Search'"`、
* `<component :is="item.icon">`),Element Plus 的 `el-button` / `el-menu-item`
* 会用 `<component :is="'Odometer'">` 去解析**全局组件名**,因此图标必须以全局组件存在。
*
* 新增视图时若用了新图标,`scripts/check-icons.mjs` 会在构建前报错(见 package.json 的 build 脚本),
* 不会静默渲染成空白。
