fix: use start scripts instead of restart in menu to support multi-instance (#102)

- Extract menu generation logic into standalone refresh-menu.sh script
- Use inotifywait to watch ~/Desktop/ for .desktop file changes and
  auto-refresh the openbox right-click menu on app install/uninstall
- Add inotify-tools to Dockerfile dependencies
- Add 'Installing Third-Party Applications' section to both READMEs
  documenting how to install apps like Telegram via sidebar panel

+## WHERE TO LOOK
+
+| 任务 | 位置 | 备注 |
+|------|------|------|
+| 添加新应用 | `Dockerfile` (安装) + `root/defaults/menu.xml` (菜单) | 参考 QQ 安装段落的 case 模式 |
+| 修改启动行为 | `root/scripts/start.sh` | 入口脚本，由 `root/defaults/autostart` 触发 |
+| 修改右键菜单 | `root/defaults/menu.xml` + `root/scripts/refresh-menu.sh` | menu.xml 是模板，refresh-menu.sh 动态合并 ~/Desktop/*.desktop |
+| 修改菜单动态生成逻辑 | `root/scripts/refresh-menu.sh` | 解析 .desktop 文件的 Name/Exec/Icon 字段，处理图标搜索 |
+| 添加新应用启动/重启脚本 | `root/scripts/<app>/` | 遵循 wechat/ 目录模式: start.sh + restart.sh |
+| 修改环境变量 | `Dockerfile` (ENV) + `docker-compose.yml` (environment) | 两处需同步 |
+| CI/CD | `.github/workflows/docker.yml` | tag v* 触发，多架构 buildx，可选推送 Docker Hub |
+| Issue 自动化 | `.github/workflows/issue-validation.yml` + `cleanup-issues.yml` | 标题/描述校验 + 7天自动关闭 |
+
+## CONVENTIONS
+
+- **语言**: 脚本用 Bash (#!/bin/bash)，窗口切换器用 Python3 + Xlib + tkinter
+- **容器路径约定**: `COPY /root /` 将 `root/` 目录内容映射到容器根 `/`，因此 `root/scripts/start.sh` → 容器内 `/scripts/start.sh`
+- **自启动机制**: Selkies 基础镜像读取 `/defaults/autostart` 文件执行启动脚本
+- **菜单刷新**: inotifywait 监听 `~/Desktop/` 变更自动刷新 Openbox 菜单
+- **进程管理**: 应用通过 `nohup ... &` 后台启动，restart 脚本先 `pkill -9` 再启动
+- **restart 脚本模式**: `pkill -9 -f /usr/bin/<app>` → `nohup /usr/bin/<app> >/dev/null 2>&1 &`（QQ 需额外 `--no-sandbox`）
+- **菜单模板 vs 运行时**: `root/defaults/menu.xml` 是源码模板，`/config/.config/openbox/menu.xml` 是运行时生成的，不要混淆
+- **refresh-menu.sh**: 仅在内容变更时才写入 + reconfigure，避免无意义刷新
+- **图标搜索优先级**: proot-apps icons (256→512→128→64→48→scalable) → system icons → fallback xterm icon
+- **多架构**: Dockerfile 使用 `$TARGETPLATFORM` 条件分支安装不同架构 deb 包
+
+## ANTI-PATTERNS (THIS PROJECT)
+
+- **不要直接修改 `config/` 目录下的文件** — 这是运行时挂载数据，gitignored
+- **不要修改 `config/.config/openbox/` 下文件作为"源码"** — 这些由 `root/defaults/` 模板生成
+- **不要在 `root/` 下放非容器必需文件** — `COPY /root /` 会将所有内容复制到容器根目录
+- **不要在 menu.xml 中添加 .desktop 动态条目** — 由 refresh-menu.sh 自动处理
+- **不要在 start.sh 中用 `exec` 替代 `nohup ... &`** — 需要多进程并行运行
+- **升级后功能缺失** → 清空 `./config/.config/openbox/` 目录（已知 gotcha，见 README）
+- **window_switcher.py 已废弃** — `start.sh` 中已注释掉，但文件保留，不要删除
+
+## COMMANDS
+
+```bash
+# 本地构建并启动
+docker-compose up -d --build
+
+# 仅启动（使用已有镜像）
+docker-compose up -d
+
+# 查看日志
+docker-compose logs -f wechat-selkies
+
+# 进入容器调试
+docker exec -it wechat-selkies bash
+
+# 清理升级问题
+rm -rf ./config/.config/openbox
+```
+
+## NOTES
+
+- 端口 3000=HTTP, 3001=HTTPS（推荐 HTTPS）
+- `shm_size: "1gb"` 影响 WebRTC 性能，建议保留
+- `/dev/dri` 映射为可选 GPU 加速
+- `AUTO_START_WECHAT` / `AUTO_START_QQ` 控制容器启动时是否自动拉起应用
+- 第三方应用通过 proot-apps 安装，快捷方式自动出现在右键菜单
+- Docker Hub 推送需在 GitHub 仓库 Environment 中配置 `ENABLE_DOCKERHUB=true`

+## 安装第三方应用（如 Telegram）
+
+本项目支持通过 [proot-apps](https://github.com/linuxserver/proot-apps) 安装第三方 Linux 应用。以 Telegram 为例：
+
+1. 在浏览器中打开容器桌面
+2. 点击左侧 **侧边栏** → **应用程序**（Applications）
+3. 在应用列表中找到 **Telegram**
+4. 点击 **安装**（Install）按钮，等待安装完成
+
+安装完成后，应用快捷方式会自动出现在 `~/Desktop/` 目录下，**右键菜单会自动刷新**，无需重启容器即可从菜单中启动该应用。
+
+> **提示：** 如需卸载应用，同样通过侧边栏 → 应用程序，选中对应应用后点击 **卸载**（Uninstall）即可，右键菜单会自动更新。

+## Installing Third-Party Applications (e.g., Telegram)
+
+This project supports installing third-party Linux applications via [proot-apps](https://github.com/linuxserver/proot-apps). Here's how to install Telegram as an example:
+
+1. Open the container desktop in your browser
+2. Click the **Sidebar** on the left → **Applications**
+3. Find **Telegram** in the application list
+4. Click the **Install** button and wait for the installation to complete
+
+Once installed, the application shortcut will automatically appear in the `~/Desktop/` directory, and the **right-click menu will auto-refresh** — no container restart needed to launch the app from the menu.
+
+> **Tip:** To uninstall an application, go to Sidebar → Applications, select the app, and click **Uninstall**. The right-click menu will update automatically.
