Fix electron-builder packaging errors

🔧 **Package.json Fixes:**
- Add required description for electron-builder
- Add author information with email for Linux .deb packages
- Add Linux maintainer field to fix .deb build error
- Remove icon references (using default icons for now)

📁 **Assets Directory:**
- Create assets/ directory structure
- Add README.md with icon requirements and guidelines
- Prepare for future custom app icons

✅ **Build Fixes:**
- Resolves "Please specify author 'email'" error
- Fixes Linux .deb package maintainer requirement
- Removes missing icon file warnings
- Maintains all platform build targets

This should resolve the CI/CD build failures and allow successful
cross-platform packaging.
