gt-node: initializeGT() does not auto-read GT_API_KEY from environment

[moss-bryophyta]

Problem

The gt-node quickstart instructs users to set GT_API_KEY in a .env file, but initializeGT() does not automatically read it from process.env. The example only passes projectId: process.env.GT_PROJECT_ID — not the API key.

When following the quickstart exactly, the server logs:

I18nManager: devApiKey or apiKey is required

And translations do not work.

Expected behavior

initializeGT() should auto-read GT_API_KEY from process.env (similar to how it reads GT_PROJECT_ID), or the quickstart should explicitly pass devApiKey: process.env.GT_API_KEY.

Steps to reproduce

1. Follow the gt-node quickstart exactly
2. Set GT_API_KEY and GT_PROJECT_ID in .env
3. Run the full example Express server
4. Observe the warning and no translations
