**refactor(demo): update logging and function descriptions for consistency**

### Changes:
- **simplified-augmentations.js**:
  - Updated comments and console logs to replace "examples" with "demo" for consistent terminology.
  - Adjusted function description and logging messages to align with the recent folder structure changes.

- **Renamed**:
  - `examples/simplified-augmentations.js` → `demo/simplified-augmentations.js`.
  - `examples/demo.html` → `demo/index.html`.

### Purpose:
Revised terminology and logging outputs to reflect the updated folder structure and naming conventions. Improved clarity and consistency across file comments and logs.
