 * BrowserManager - Singleton manager for Local Browser instance
 *
 * This class implements the Singleton pattern to ensure only one browser instance
 * exists across the application. It provides:
 *
 * 1. Lazy initialization - browser only launches when first needed
 * 2. Lifecycle management - handling browser creation, verification and cleanup
 * 3. Global access - consistent access point to shared browser instance
