Same-day hotfix reverts a v2.1.265 regression where CLAUDE_CODE_USE_GATEWAY wrongly forced Cloud-gateway sign-in, breaking proxy/API-key setups.
CLAUDE_CODE_USE_GATEWAY environment variable, previously ignored unless ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN were both set, began forcing Cloud-gateway sign-in on its own in 2.1.265, so configurations that set it alongside an API key, apiKeyHelper, or custom auth headers failed every request with "Not signed in to the Cloud gateway". The variable on its own is ignored again; no configuration change is needed
