[BUG] Auto-update never worked

Environment

• Platform (select one):
  • [x] Anthropic API
  • [ ] AWS Bedrock
  • [ ] Google Vertex AI
  • [ ] Other:
• Claude CLI version: 0.2.102 (Claude Code)
• Operating System: macOS 15.4.1
• Terminal: iTerm2

Bug Description

I see Auto-updating to v0.2.103… message upon entering the CLI, then ✓ Update installed · Restart to apply. However, after exiting the CLI (with ctrl+c or /exit) and re-entering the CLI, it's still on v0.2.102 and it's attempting to auto-update to v0.2.103 again. Running npm install -g @anthropic-ai/claude-code actually updates it.
