Module auth 

Auth module — credential types, security schemes, and auth configuration.

This module provides the full ADK-JS-compatible authentication type hierarchy:

• AuthCredential and AuthCredentialType — credential storage
• AuthScheme — OpenAPI 3.0-style security scheme definitions
• AuthConfig — binds a scheme to credentials
• AuthToolArguments — passed to tools when auth is required
