fix: proxy googleapis.com through Cloudflare and fix fetch duplex for POST streaming

- Add googleapis.com to default CLOUDFLARE_PROXY_DOMAINS so Gemini API
calls route through CF Worker instead of going direct (HF blocks direct
connections to generativelanguage.googleapis.com)
- Fix duplex:"half" placement in patched fetch — must be a fetch() init
option not a Request constructor option; Node.js/undici only reads it
from fetch opts, causing POST streaming bodies to fail immediately
