磁盘空间分析清理

Please show my disk usage:
- Total capacity, used, and available space
- Usage percentage
- If there are multiple partitions, show each separately

Please analyze space usage in ~/ home directory:
- List the top 20 folders by space usage
- Show sizes in human-readable format (GB, MB)
- Sort in descending order by size

Find all files larger than 100MB in ~/ directory:
- Show file path, size, and last modification time
- Sort by size
- Identify file types (video, archives, disk images, etc.)
- Mark which might be temporary files or caches
