feat: add quick command reference to guide, SSH support, and handoff doc

- Add copy-paste command reference card to guide.html Linux section
- Add enable-ssh.sh standalone script for remote access on Live USB
- Add optional SSH install prompt to setup-openclaw.sh
- Add HANDOFF.md for Mac mini Claude Code remote takeover

+# Handoff Document — U-Claw Linux Remote Access
+
+## Current Status
+
+- U盘已就绪：Ventoy + Ubuntu 24.04 ISO + persistence + u-claw-linux scripts
+- 所有源码已推送到 GitHub main 分支
+- website/guide.html 已添加快速命令参考卡片
+- enable-ssh.sh 已添加到 bootable/linux-setup/
+
+## Linux 启动后需要做的事
+
+1. 从 U 盘启动 → Ventoy 菜单选 Ubuntu
+2. 如果首次使用，格式化持久化：
+   ```
+   sudo bash /media/*/Ventoy/u-claw-linux/format-persistence.sh
+   ```
+   然后重启
+3. 连接 WiFi
+4. 安装 OpenClaw：
+   ```
+   sudo bash /media/*/Ventoy/u-claw-linux/setup-openclaw.sh
+   ```
+5. 启用 SSH（让 Mac mini 远程控制）：
+   ```
+   sudo bash /media/*/Ventoy/u-claw-linux/enable-ssh.sh
+   ```
+
+## SSH 连接信息
+
+- **用户名**: ubuntu (Live USB 默认用户)
+- **密码**: 运行 enable-ssh.sh 时设置
+- **IP 地址**: 运行 enable-ssh.sh 后会显示，格式类似 192.168.x.x
+- **前提**: 两台机器在同一个 WiFi/局域网下
+
+## Mac mini Claude Code 接手方法
+
+1. 用户在 Linux 上运行 `enable-ssh.sh`，获取 IP 和设置密码
+2. 用户告诉 Mac mini 上的 Claude Code：IP 地址和密码
+3. Mac mini Claude Code 通过 Bash 工具执行：
+   ```
+   ssh ubuntu@<IP> 'command'
+   ```
+   或建立持久连接进行调试
+
+## 文件位置（Linux 上）
+
+| 路径 | 说明 |
+|------|------|
+| `/media/*/Ventoy/u-claw-linux/` | U 盘上的脚本 |
+| `/opt/u-claw/` | 安装后的 OpenClaw |
+| `/opt/u-claw/start-openclaw.sh` | 启动脚本 |
+| `/opt/u-claw/data/.openclaw/openclaw.json` | 配置文件 |
+
+## 注意事项
+
+- Live USB 每次重启后，除了持久化分区内的数据，其他都会重置
+- SSH server 需要每次重启后重新安装（除非持久化生效）
+- 持久化生效后，apt 安装的包会保留
