[sdk] Angular Wrapper (@reviewskits/angular)

[FranklinCODEX]

What problem does this solve?

Angular developers currently have no native integration for Reviewskits. An Angular-specific wrapper will provide the necessary services and modules to integrate reviews into Angular applications using standard patterns (Directives, Services, RxJS).

Proposed solution

Create the @reviewskits/angular package.

1. Service-based Architecture: Implement a ReviewsKitService that wraps @reviewskits/core.
2. RxJS Integration: Provide observable-based APIs for fetching reviews and monitoring status.
3. Module/Standalone: Support both the classic NgModule and the new standalone component pattern.
4. Directives: (Optional) Provide directives for easy review display.

Alternatives considered

• Direct Core usage: Using the core SDK with fromPromise in every component.

Who does this benefit?

• Developers using the SDK
• Admins using the dashboard
• DevOps / self-hosters

This is a great opportunity for community contribution. We should provide a clear starting guide for Angular developers.
