[BUG] claude --ide fails on WSL2 as JetBrains Rider appears twice in IDE list

What's Wrong?

Description:

When running on WSL2 with JetBrains Rider installed on Windows, /ide shows Rider as two separate
entries, even though they select as one (arrows on both at the same time). Since claude --ide requires
exactly one valid IDE to auto-connect, it fails to connect because it detects two.

Environment:

• WSL2 (Linux 6.6.87.2-microsoft-standard-WSL2)
• JetBrains Rider 2025.3.3 with Claude Code plugin on Windows 11
• Claude Code CLI

What Should Happen?

Rider should appear once, or claude --ide should handle duplicate entries for the same IDE.
