/heapdump fails on Windows: EEXIST mkdir 'C:\Users\<username>\Desktop'

Bug Report

Command: /heapdump

Error:

Failed to create heap dump: EEXIST: file already exists, mkdir 'C:\Users\<username>\Desktop'

Environment:

• OS: Windows 11 Home (10.0.26200)
• Claude Code version: 2.1.72
• Shell: bash (Git Bash)

Description:
The /heapdump command fails because it tries to mkdir on the Desktop path, which already exists as a directory. It doesn't handle the case where the directory already exists (missing { recursive: true } or equivalent check).
