**refactor(cli): reformat logging and descriptions for improved readability**

### Changes:
- **src/cli.ts**:
  - Reformatted multi-line logging statements using consistent indentation for better readability.
  - Reformatted `import-sparse` command description for consistent line wrapping.
  - Adjusted function definitions and options configurations for clarity.
  - Improved inline comments (`examples` → `demo`) for accurate context.

### Purpose:
Enhanced code readability and consistency by reformatting logging, descriptions, and comments. Improved maintainability through structured formatting and updated context-specific references.
