Feature request: Add OpenAI's Oauth2 based login as an auth feature, similar to the Claude Pro/Max login method #1839

One way to do this would be do copy creds from ~/.codex/auth.json.

AFAIK (from reading Codex source code), this is how codex handles this:

• Changes the base URL to https://chatgpt.com/backend-api/codex
• Adds an authorization token to the request: Authorization: Bearer <access_token> (JWT from OAuth)
• Adds an extra header to the frequest: chatgpt-account-id: <account_id from auth json>

Would love to make a PR if this would be a welcome addition. Would you want to support this?
