**feat(brainy-models): enhance workflows, update README, and improve model compatibility**

- **Scripts**:
  - Refactored logging within `release-workflow.js` for improved readability and maintainability.
  - Added a fallback mechanism in `download-full-models.js` to inject the "format" field into `model.json` for TensorFlow.js compatibility.

- **Documentation**:
  - Updated `README.md` with a redesigned structure:
    - Enhanced readability using emojis and a cleaner presentation.
    - Expanded `Overview`, `Features`, and `Quick Start` sections.
    - Refined "Use Cases" and added better explanations for bundled model benefits.

- **Models**:
  - Adjusted `model.json` to include the "format" field for compatibility with TensorFlow.js.
  - Updated `metadata.json` with a recent download timestamp.

**Purpose
