    Class PromiseObservableAnalysisRule

    Analysis rule angular:promise-vs-observable-anti-pattern: reports code that converts RxJS Observables to Promises and loses cancellation, retry and composition:

    1. .toPromise() calls in any class.
    2. async methods of @Component classes.
    3. @Injectable methods returning Promise<T> that wrap HttpClient calls.
    4. Several sequential awaits in one method.
    5. Manual detectChanges() calls after await.
    const rule = new PromiseObservableAnalysisRule();
    const violations = await rule.analyze(context);
