initial: 七牛云上传 OpenClaw Skill

功能特性:
- 支持 /upload, /u 命令上传文件到七牛云
- 支持 /qiniu-config 配置管理
- 支持飞书卡片交互
- 支持指定上传路径和存储桶
- 自动刷新 CDN 缓存
- 支持文件覆盖上传

包含组件:
- OpenClaw 处理器 (openclaw-processor.js)
- 独立监听器 (scripts/feishu-listener.js)
- 核心上传脚本 (scripts/upload-to-qiniu.js)
- 部署脚本 (deploy.sh)
- 完整文档

部署方式:
1. 复制 skill 到 ~/.openclaw/workspace/skills/
2. 配置 ~/.openclaw/credentials/qiniu-config.json
3. 重启 OpenClaw Gateway

openclaw-handler.js
