Module auth 

Authentication utilities for VT Code.

This module provides:

• Generic credential storage with OS keyring and file backends
• OAuth PKCE support for OpenRouter and other providers

Credential Storage

Credentials are stored using OS-specific secure storage (keyring) by default, with fallback to AES-256-GCM encrypted files if the keyring is unavailable.
