Authentication

This adapter supports two authentication methods:

1. Explicit Credentials: Pass projectId, clientEmail, and privateKey to the constructor
2. Application Default Credentials (ADC): If credentials are not provided, the adapter will use ADC. This is useful when running on Google Cloud infrastructure or when you have configured GOOGLE_APPLICATION_CREDENTIALS environment variable
