**feat(utils): add type utility functions and examples for runtime type management**

- Introduced `getNounTypes`, `getVerbTypes`, `getNounTypeMap`, and `getVerbTypeMap` utilities for managing noun and verb types at runtime.
- Added comprehensive unit tests (`type-utils.test.ts`) to ensure correctness of type utility functions.
- Created new example files (`type-utils-example.js`, `type-utils-example.ts`) to demonstrate the use of type utilities in JavaScript and TypeScript environments.
- Updated `README.md` with detailed documentation and usage examples for the new type utilities.
- Enhanced `index.ts` to export the new utility functions, making them accessible throughout the library.

**Purpose**: Facilitate easy access, validation, and manipulation of noun and verb types in client applications, providing better runtime type management.
