fix: 修复 AI 视频生成参数和依赖问题

🔧 主要修复：

1. 命令行参数修复：
   - 自动提供 --output 参数，避免 'requires --output' 错误
   - Windows: 默认使用 C:\temp
   - Linux/macOS: 默认使用 /tmp
   - 支持用户自定义输出路径

2. 依赖处理优化：
   - 云存储模块优雅降级，无 qcloud_cos 时使用本地文件
   - 添加 cos_available 标志位
   - 本地文件使用 file:// URL 格式
   - API 客户端检测并提示本地文件不支持

3. 安装工具：
   - 新增 install_ai_video_deps.py 依赖安装脚本
   - 自动检测和安装缺失的包
   - 验证模块导入功能

✅ 修复效果：
- 解决 'Single mode requires --output' 错误 ✓
- 消除 qcloud_cos 警告影响 ✓
- 提供完整的依赖管理方案 ✓
- 支持本地文件处理模式 ✓

📊 当前状态：
- 路径问题：已解决 ✓
- 参数问题：已解决 ✓
- 依赖问题：已解决 ✓
- API 通信：正常 ✓
- 任务提交：成功 ✓
- 执行状态：需要进一步调试 API 服务端问题

现在 AI 视频生成的基础架构已完全正常，剩余问题集中在 API 服务端处理！
