Video Generator

Please help me install the Video Generator skill for ZhenSkill.

First, check if ClawHub CLI is installed:
```bash
clawhub --version
```

If the command is not found, install the CLI:
```bash
curl -fsSL https://www.zhenskill.com/install.sh | bash
```

Then restart your terminal or run:
```bash
source ~/.bashrc  # or ~/.zshrc for Zsh
```

Install the video-generator skill:
```bash
clawhub install video-generator
```

Verify the installation:
```bash
clawhub list | grep video-generator
```

You should see "video-generator" in the output.
