feat: 添加捞虾功能（自动扫描 Agent）🦐

🎯 新功能：
- 捞虾按钮：自动扫描 Docker 容器和宿主机进程
- 发现 openclaw 相关的 Agent 实例
- 自动创建或更新 Agent 记录
- 过滤掉没有端口的'石头'（无效进程）

🦐 捞虾逻辑：
1. 扫描 Docker 容器（跳过数据库、网关等辅助容器）
2. 扫描宿主机进程（ps aux）
3. 从容器名/进程名推断 Agent 名称和专长
4. 提取端口信息
5. 只保存有端口的有效 Agent

✨ 优化：
- 处理复杂的容器名称（如 openclaw-instance2-openclaw-cn-gateway-1）
- 自动推断 Emoji 和专长
- 避免重复创建

📊 捞虾结果：
- 显示捞到的虾数量
- 显示新增和更新数量
- 区分 Docker 容器和宿主机进程

🎨 界面：
- 按钮文案：'🦐 捞虾' / '🦐 捞虾中...'
- 提示信息生动有趣
- 加载状态显示

🐛 修复：
- 不过滤 gateway/watcher 容器（可能包含 Agent）
- 只跳过数据库容器（postgres/db/redis）

🦸 感谢北极星 ⭐ 的'捞虾'命名灵感！
