IDE integration: WSL path not matched to Windows working directory

Description

When using /ide with JetBrains Rider on Windows, the path comparison fails because Rider reports the project path in WSL format (/mnt/c/github/Massient/MassTransit) while Claude Code's working directory uses the Windows format (C:\github\Massient\MassTransit).

These refer to the same directory, but the match fails and Claude Code complains the path doesn't match the project.

Steps to reproduce

1. Open a project in JetBrains Rider on Windows (e.g. C:\github\Massient\MassTransit)
2. Run Claude Code in the same directory
3. Use /ide to connect to Rider
4. Rider reports its path as /mnt/c/github/Massient/MassTransit
5. Claude Code rejects it as not matching the project

Expected behavior

Path normalization should handle the WSL (/mnt/c/...) to Windows (C:\...) mapping (and vice versa) before comparing paths.

Environment

• Windows 11 Pro
• JetBrains Rider
• Claude Code CLI
