[BUG] Windows path parsing error - extra "c" character inserted in drive path

Bug Report

Environment:

• OS: Windows (win32) win 10
• Claude Code version: Latest 1.0.92 (Claude Code)
• Working directory: C:\Users\admin\Documents\Obsidian-xx
• Repository: Git repository (confirmed via Is directory a git repo: Yes)

Issue:
Claude Code is incorrectly parsing Windows drive paths by inserting an extra "c" character, resulting in malformed paths that cannot be found.

Expected behavior:
Claude should correctly reference the path:
C:\Users\admin\Documents\Obsidian-xx\02-STRUMENTAZIONE\Kit-e-Accessori

Actual behavior:
Claude reports the path as:
C:\c\Users\admin\Documents\Obsidian-xx\02-STRUMENTAZIONE\Kit-e-Accessori

Error message:
Path C:\c\Users\admin\Documents\Obsidian-xx\02-STRUMENTAZIONE\Kit-e-Accessori was not found.

Steps to reproduce:

1. Initialize Claude Code in a Windows directory with subdirectories
2. Navigate or reference paths within the repository
3. Observe the malformed path with extra "c" character

Verification:
The correct path exists and is accessible - confirmed via LS tool:

• ✅ C:\Users\admin\Documents\Obsidian-xx\02-STRUMENTAZIONE\Kit-e-Accessori (exists)
• ❌ C:\c\Users\admin\Documents\Obsidian-xx\02-STRUMENTAZIONE\Kit-e-Accessori (malformed)

Impact:
This prevents Claude from correctly accessing existing directories and files, causing "path not found" errors for valid Windows paths.

Additional context:
This appears to be a path parsing issue specific to Windows drive letters where the drive letter "C" is being duplicated in the path construction.
