Module client 

OAuth 2.0 Client Implementation

This module provides a proven OAuth 2.0 client wrapper that supports:

• Authorization Code flow (with PKCE)
• Client Credentials flow (server-to-server)
• Device Authorization flow (CLI/IoT)

The client handles provider-specific configurations and quirks for Google, Microsoft, GitHub, GitLab, and generic OAuth providers.
