    Class PresentationalComponentViolationRule

    Analysis rule angular:presentational-component-violation: reports components that should be presentational but contain business logic, service dependencies or state management. Presentational components render UI and leave business logic to their container components, communicating through inputs and outputs.

    Detection targets:

    1. Business service dependencies injected via constructor or inject().
    2. .subscribe() calls in lifecycle hooks without takeUntilDestroyed.
    3. Methods calling services without a matching @Output or output().
    4. Business logic methods (name keyword plus more than 3 branching tokens).
    5. Complex local state (arrays, Maps, Sets in 3 or more non-input properties).

    Dialog components (see DialogDetectionConfig) are skipped.

    const rule = new PresentationalComponentViolationRule();
    const violations = await rule.analyze(context);
    // violations contain service-dependency, subscription-in-lifecycle,
    // missing-output, business-logic, complex-state-management entries
