feat: improve Cloudflare Temp Email random subdomain support and sidepanel UX

- 合并 PR #136 的核心改动：补充 Cloudflare Temp Email 随机子域支持、独立侧边栏卡片与使用教程入口
- 本地补充修复：恢复注册诊断测试中的可读中文触发词，并同步 docs/使用教程.md 到结构文档
- 影响范围：generated email helpers、sidepanel Cloudflare Temp Email 配置、signup diagnostics tests、docs

+# Codex 注册扩展更新与 Clash Verge 非港轮询配置教程
+
+本教程用于说明如何更新 `Codex 注册扩展`，以及如何在 `Clash Verge` 中配置 `🔁 非港轮询`。
+
+## 适用场景
+
+- 已经安装本扩展，想更新到最新版本
+- 想用更方便的方式长期同步扩展更新
+- 需要在 `Clash Verge` 中启用 `🔁 非港轮询`
+
+## 准备内容
+
+- 已安装好的扩展文件夹
+- 可以打开浏览器的 `扩展程序管理` 页面
+- 如需使用 `git pull`，本地已安装 `git`
+- 如需使用 `GitHub Desktop`，本地已安装 `GitHub Desktop`
+- 已安装 `Clash Verge`，并已导入可用订阅
+
+## 操作步骤
+
+### 第一部分：更新扩展
+
+1. 使用 `GitHub Desktop` 更新  
+   先安装 `GitHub Desktop`。  
+   把当前扩展仓库交给 `GitHub Desktop` 管理后，之后就可以随时更新。  
+   `GitHub Desktop` 的具体使用方法本教程不展开，需要时可直接询问豆包。
+
+2. 使用 `git pull` 更新（最方便，最推荐）  
+   先在本地安装 `git`。  
+   打开终端后执行 `cd 扩展文件夹路径` 进入当前扩展目录。  
+   接着执行 `git pull` 拉取最新更新。  
+   这是最方便、最推荐的更新方式。
+
+3. 手动下载最新版本覆盖更新  
+   点击左上角的版本号或 `更新` 按钮。  
+   下载最新版本到本地后，直接覆盖现有扩展文件夹即可。
+
+4. 更新完成后重新加载扩展  
+   不论使用哪种更新方式，更新完成后都必须打开浏览器的 `扩展程序管理` 页面。  
+   找到该扩展后，手动点击一次 `重新加载`。  
+   这一步一定要做，否则浏览器可能仍在使用旧版本。
+
+### 第二部分：配置 `Clash Verge` 的 `🔁 非港轮询`
+
+#### 第一步：添加扩展脚本
+
+1. 打开 `Clash Verge`，进入左侧的 `订阅`（`Profiles`）界面。
+2. 在右上角或对应位置找到并双击打开 `全局扩展脚本`（`Merge/Script`）。
+3. 将里面的内容全部清空，替换为下方格式化好的代码。
+4. 点击保存，使用右上角保存按钮或按 `Ctrl+S`。
+
+💻 格式化后的代码（如果遇到格式错误，则让豆包修复一下）
+
+```javascript
+function uniqPrepend(arr, items) {
+  if (!Array.isArray(arr)) arr = [];
+  for (var i = items.length - 1; i >= 0; i--) {
+    var item = items[i];
+    var exists = false;
+    for (var j = 0; j < arr.length; j++) {
+      if (arr[j] === item) {
+        exists = true;
+        break;
+      }
+    }
+    if (!exists) arr.unshift(item);
+  }
+  return arr;
+}
+
+function upsertGroup(groups, group) {
+  for (var i = 0; i < groups.length; i++) {
+    if (groups[i] && groups[i].name === group.name) {
+      groups[i] = group;
+      return groups;
+    }
+  }
+  groups.unshift(group);
+  return groups;
+}
+
+function main(config, profileName) {
+  if (!config) return config;
+
+  if (!Array.isArray(config["proxy-groups"])) {
+    config["proxy-groups"] = [];
+  }
+
+  var groups = config["proxy-groups"];
+  var LB_NAME = "🔁 非港轮询";
+
+  var excludeRegex =
+    "(?i)(" +
+    "香港|hong[ -]?kong|\\bhk\\b|\\bhkg\\b|🇭🇰" +
+    "|剩余流量|套餐到期|下次重置剩余|重置剩余|到期时间|流量重置" +
+    "|traffic|expire|expiration|subscription|subscribe|reset|plan" +
+    ")";
+
+  groups = upsertGroup(groups, {
+    name: LB_NAME,
+    type: "load-balance",
+    strategy: "round-robin",
+    "include-all-proxies": true,
+    "exclude-filter": excludeRegex,
+    url: "https://www.gstatic.com/generate_204",
+    interval: 300,
+    lazy: true,
+    "expected-status": 204
+  });
+
+  var injected = false;
+  var entryNameRegex = /节点选择|代理|Proxy|PROXY|默认|GLOBAL|全局|选择/i;
+
+  for (var i = 0; i < groups.length; i++) {
+    var g = groups[i];
+    if (!g || g.type !== "select") continue;
+
+    if (entryNameRegex.test(g.name || "")) {
+      if (!Array.isArray(g.proxies)) g.proxies = [];
+      g.proxies = uniqPrepend(g.proxies, [LB_NAME]);
+      injected = true;
+    }
+  }
+
+  if (!injected) {
+    for (var k = 0; k < groups.length; k++) {
+      var g2 = groups[k];
+      if (g2 && g2.type === "select") {
+        if (!Array.isArray(g2.proxies)) g2.proxies = [];
+        g2.proxies = uniqPrepend(g2.proxies, [LB_NAME]);
+        break;
+      }
+    }
+  }
+
+  config["proxy-groups"] = groups;
+  return config;
+}
+```
+
+#### 第二步：应用设置
+
+1. 切换到左侧的 `代理`（`Proxies`）界面，也就是首页。
+2. 在顶部的分类中，通常会看到 `节点选择`、`Proxy` 或 `当前节点` 之类的分组。
+3. 在对应下拉框中选择 `🔁 非港轮询`。
+4. 确认右上角的 `代理模式`（`Mode`）已经设置为 `规则模式`（`Rule`）。
+5. 确认左侧 `设置` 中的 `系统代理`（`System Proxy`）已经开启。
+
+
+## 注意事项
+
+- 不论使用哪种方式更新扩展，更新完成后都必须在浏览器的 `扩展程序管理` 页面重新加载一次该扩展。
+- 如果你长期更新扩展，优先使用 `git pull`，这是最方便、最推荐的方式。
+- 使用手动覆盖更新时，请直接覆盖当前扩展文件夹，避免同时保留多份不同版本的目录。
+- 在 `Clash Verge` 中粘贴脚本时，请先清空旧内容，再完整粘贴新代码并保存。
