/**
 * @angular-modernizer/plugin-angular - Unnecessary Change Detection Rule
 *
 * Detects Angular components using Default change detection unnecessarily.
 * Components should use OnPush change detection when possible for better performance.
 *
 * Detection Patterns:
 * - Components with @Input properties using Default change detection
 * - Components with complex logic using Default change detection
 * - Components that could benefit from OnPush but don't use it
 *
 * This rule promotes better performance by encouraging OnPush change detection.
