✨ Feature Request: Create useAA v2.x for Nexus SDK

# ✨ Feature Request: `useAA` v2 React Hooks Library for Nexus SDK

## What

Extend and enhance the existing `useAA` React Hooks library to support the Nexus SDK functionalities, effectively making it the next iteration of `useAA`. This includes integrating the module-based architecture of the Nexus SDK and providing hooks for new features while maintaining backward compatibility where possible.

## Why

- **Leverage Existing Work**: Building upon the established `useAA` library reduces duplication of effort and capitalizes on its existing features and user base.
- **Seamless Transition**: Provides a smooth upgrade path for developers already using `useAA`, encouraging adoption of the Nexus SDK.
- **Consistent Developer Experience**: Maintains familiar APIs and patterns to lower the learning curve.
- **Enhance Functionality**: Incorporates the advanced features of the Nexus SDK, such as smart sessions, passkey authentication, and module interactions.
- **Community Engagement**: Encourages contributions by building upon a known and trusted library within the community.

## How

1. **Evaluate the Current `useAA` Library**

- Review the existing `useAA` codebase to understand its architecture and functionalities.
- Identify areas that need modification or extension to support the Nexus SDK.

2. **Plan Integration with Nexus SDK**

- Map `useAA` functionalities to the Nexus SDK equivalents.
- Design how to integrate the module-based architecture and new features of the Nexus SDK into the hooks.

3. **Update Existing Hooks**

- Refactor existing hooks (e.g., `useSmartAccount`, `useSendTransaction`) to interact with the Nexus SDK instead of or in addition to the previous SDK.
- Ensure compatibility with the Nexus SDK's API and data structures.

4. **Implement New Hooks for Nexus SDK Features**

- Develop hooks for new functionalities introduced in the Nexus SDK:
- `useSession`: Manage smart sessions with support for USE and ENABLE modes.
- `usePasskey`: Handle passkey authentication flows.
- `useModule`: Interact with various Nexus SDK modules.
- `usePermission`: Manage permissions within the app.

5. **Maintain Backward Compatibility**

- Aim to keep existing hook APIs unchanged where possible to prevent breaking changes.
- Provide deprecation warnings and migration guides for any necessary changes.

6. **Enhance Documentation**

- Update the `useAA` README and documentation to reflect the new features and changes.
- Include migration guides for existing users to transition smoothly.
- Provide comprehensive examples showcasing both old and new functionalities.

7. **Update Examples and Tutorials**

- Revise existing examples to use the updated hooks and Nexus SDK.
- Create new examples demonstrating how to use Nexus SDK-specific features.

8. **Testing**

- Write unit and integration tests for new and updated hooks.
- Ensure thorough coverage of interactions with the Nexus SDK.
- Use testing tools like Jest and React Testing Library.

9. **Package and Release**

- Decide whether to release this as a new major version of `useAA` (e.g., `useAA` v2.0.0) or as a new package name (e.g., `useNexus`).
- Update package metadata, versioning, and change logs accordingly.
- Publish the updated package to npm.

10. **Community Communication**

- Communicate the updates to the community through blog posts, social media, and developer forums.
- Encourage feedback and contributions.
- Provide support channels for users upgrading to the new version.
