/**
* OAuth 2.0 Authorization Server implementation for MCP
*
* This module implements OAuth endpoints that allow ChatGPT (or other MCP clients)
* to authenticate users via Google OAuth.
*
* Flow:
* 1. ChatGPT calls /.well-known/oauth-authorization-server to discover endpoints
* 2. ChatGPT redirects user to /authorize
* 3. /authorize redirects user to Google OAuth
* 4. Google redirects back to /callback with authorization code
* 5. /callback redirects to ChatGPT with our own code
* 6. ChatGPT calls /token to exchange code for tokens
* 7. /token exchanges our code for Google tokens and returns them
