[BUG] Can't log out of Claude Code API Key usage or use Vertex AI

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [x] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.3 (Claude Code)
• Operating System: macOS 14.6.1 (23G93
• Terminal: Warp

Bug Description

Vertex AI settings not available, can't log out from using API key

Steps to Reproduce

I have env vars for Vertex AI set in my .zshrc, but they are ignored by Claude Code now.
export CLAUDE_CODE_USE_VERTEX=1
export CLOUD_ML_REGION=us-east5
export ANTHROPIC_VERTEX_PROJECT_ID=<project_id>
/status shows that I'm logged in using API key

 Account • /login
  L Login Method: API Key (/login managed key)

/login and /logout steps are not available

Expected Behavior

Claude Code should be using Vertex AI instead of API key
I should be able to /logout to stop using API key

Actual Behavior

I'm locked into using api key, Vertex AI settings are ignored
