Environment

• Platform (select one):
• [x] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.57+
• Operating System: Windows 10
• Terminal: PowerShell → WSL bash (via wsl -- bash -ic "claude")

Bug Description

Since claude-code version 1.0.57 and above, IntelliJ IDEA is being detected twice in the IDE selection menu, which causes the auto-connect IDE feature to fail. The IDE selection shows two identical IntelliJ IDEA entries pointing to the same path, and users must manually type and select "/ide" to proceed.

Steps to Reproduce

1. Install claude-code version 1.0.57 or higher on Windows 10
2. Open IntelliJ IDEA and navigate to the terminal
3. Run wsl -- bash -ic "claude" in the PowerShell terminal within IntelliJ IDEA
4. Observe the IDE selection menu

Expected Behavior

• IntelliJ IDEA should be detected only once in the IDE selection menu
• Auto-connect to IDE should work properly without user intervention
• The IDE integration should function seamlessly

Actual Behavior

• IntelliJ IDEA appears twice in the IDE selection list (both pointing to /mnt/c/_GITHUB/spectrakr/k8s-cluster-packages)
• Auto-connect to IDE fails due to duplicate detection
• User must manually type and select "/ide" to proceed
• The tip message suggests using --ide flag or config, but auto-connect should work by default

Additional Context

• This issue started occurring after upgrading from a version prior to 1.0.57
• Previous versions correctly detected IntelliJ IDEA only once and auto-connect worked as expected
• The terminal setup involves running claude through WSL bash from within IntelliJ's PowerShell terminal
• Both duplicate entries show the exact same path: /mnt/c/_GITHUB/spectrakr/k8s-cluster-packages
• The issue appears to be related to the IDE detection logic when running through WSL from within the IDE itself

Version comparison:

• Version 1.0.52: Auto IDE connection works fastest
• Version 1.0.56: Shows as disconnected initially with slight delay, then connects automatically
• Version 1.0.57+: Duplicate detection causes auto-connect failure, manual "/ide" input required
