Enhance project list display with descriptions and visual formatting

- Add colorful header with 📋 icon and cyan title
- Display project descriptions (previously unused)
- Add template-based icons: 🚀 content, 🔬 research, ⚙️ basic
- Format output in aligned columns with colors
- Include template type indicators in brackets
- Add usage hint for better user experience
- Improve error handling for missing jq

The 'proj' command now provides rich, informative output instead of
just listing project names.
