[BUG] JetBrains plugin path format mismatch - /mnt/c/ vs /c/ prevents IDE detection on native Windows

Preflight Checklist

What's Wrong?

Environment

• Claude Code version: 2.1.23 (native Windows install via install.ps1)
• IDE: JetBrains Rider
• Plugin: Claude Code [Beta]
• OS: Windows (native, not WSL)
• Shell: Git Bash (bundled with native install)

## Problem
The JetBrains plugin writes workspace paths in WSL format (/mnt/c/...),
but Claude Code running via Git Bash sees paths as /c/....

These are the same directory but the path formats don't match,
so IDE integration fails with "No available IDEs detected."

## Evidence
Lock file at ~/.claude/ide/62588.lock contains:
``json
{"workspaceFolders":["/mnt/c/p4/main/Svalinn"],...}
``

But Claude's working directory is: /c/p4/main/Svalinn

What Should Happen?

Expected Behavior

Claude Code should normalize paths and recognize that:

• /mnt/c/path
• /c/path
• C:\path

...are all equivalent on Windows.
