v1.2.1: fix env var conflict — ANTHROPIC_API_KEY overrides plugin fetch

When ANTHROPIC_API_KEY is set in the environment, the SDK ignores the
plugin's custom fetch and makes direct requests (no ?beta=true, no OAuth
headers). Fix: use authToken instead of apiKey, and temporarily clear
the env var during OAuth sessions.
