**chore(brainy-models): add version configuration and MIT license**

- Added `.versionrc.json` to define conventional release configurations for `brainy-models-package`:
  - Configured tag prefix as `brainy-models-v`.
  - Defined custom commit message format and section mapping for release notes.
- Added `LICENSE` file with MIT license for legal clarity.
- Updated `README.md`:
  - Adjusted internal NPM script names to use underscore prefix for consistency (`_release:patch`, `_github-release`).

**Purpose**: Establish standardized versioning, licensing, and script conventions for the `brainy-models-package` to improve maintainability and alignment with project standards.
