**docs(readme): update asset URLs and example links**

### Changes:
- **README.md**:
  - Replaced local image path for `Brainy Logo` with a GitHub raw URL to ensure accessibility in remote contexts.
  - Updated links to reference `demo` folder structure (`examples/simplified-augmentations.js` → `demo/simplified-augmentations.js`, `examples/demo.html` → `demo/index.html`).

### Purpose:
Enhanced documentation by ensuring that assets and links are accessible remotely and aligned with the recent folder structure updates. Improved clarity and consistency with the updated demo setup.
