 Uses Google OAuth with PKCE (S256) for authentication — no API key required.
 On first run, a browser opens for Google account login. Credentials (including
 refresh token) are saved to `~/.gemini/oauth_creds.json` with `0600` permissions.

 ### Cloud Code API vs standard API
 Models containing `-preview` (with hyphen) or `gemini-3` in the name, as well
 as any `gemini-` model with major version >= 2, route through the Cloud Code
 API (`cloudcode-pa.googleapis.com`) which supports SSE streaming
 and project-scoped access. Other models use the standard Generative Language
 API (`generativelanguage.googleapis.com`).
