/**
* Manual test for BrowserManager
*
* This test verifies:
* 1. Singleton pattern works correctly
* 2. Browser can be launched and connected
* 3. Stealth injection works
* 4. Browser can be restarted
* 5. Remote debugging connection works (if configured)
*
* Run with: npm run build && node build/tests/manual/test-browser-manager.js
