Fix2.1.266

Fixed 2.1.265 regression with CLAUDE_CODE_USE_GATEWAY environment variable

Fixed a regression in 2.1.265 where the CLAUDE_CODE_USE_GATEWAY environment variable was incorrectly forcing Cloud-gateway sign-in even when used with API keys or custom auth headers, causing request failures. The variable is now ignored when used alone, restoring previous behavior without requiring configuration changes.

  • Fixed a 2.1.265 regression affecting LLM-gateway and proxy setups: the undocumented 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
