 * Extracts constructor initialization logic for properties.
 *
 * Supports the following initialization patterns:
 *
 * 1. **RxJS Subjects:**
 *    ```typescript
 *    this.dataStream = new BehaviorSubject<Data>(initialData);
 *    this.events = new Subject<Event>();
 *    ```
 *
 * 2. **Dependency-based initialization:**
 *    ```typescript
 *    this.apiUrl = this.config.get('apiUrl');
 *    this.timeout = this.config.timeout || DEFAULT_TIMEOUT;
 *    ```
 *
 * 3. **Method calls:**
 *    ```typescript
 *    this.transformedData = this.processData(initialData);
 *    ```
 *
 * 4. **Complex expressions:**
 *    ```typescript
 *    this.isEnabled = environment.production && this.config.enabled;
 *    ```
 *
 * 5. **Constructor parameters:**
 *    ```typescript
 *    this.initialConfig = { ...config };
 *    ```
 *
 * @example
 * ```typescript
 * const analyzer = new ConstructorInitializationAnalyzer();
 * const inits = analyzer.extractPropertyInitializations(classDecl, ['dataStream', 'apiUrl']);
 * // Returns:
 * // [
 * //   { propertyName: 'dataStream', initializationCode: 'new BehaviorSubject<Data>(initialData)' },
 * //   { propertyName: 'apiUrl', initializationCode: "this.config.get('apiUrl')" }
 * // ]
 * ```
