[BUG] creates `tmpclaude-*-cwd` files in the current working directory

What's Wrong?

Claude Code 2.1.5 creates tmpclaude-*-cwd files in the current working directory instead of /tmp. These files are never cleaned up and accumulate in project directories.

What Should Happen?

This appears to be a regression from the original issue #8856, where files were created in /tmp/claude-*-cwd. Now they are created directly in the working directory with a different naming pattern (tmpclaude-*-cwd).

Steps to Reproduce

1. Start Claude Code in a project directory
2. Execute several bash commands
3. Check the working directory for tmpclaude-*-cwd files

Additional reproduction data:

• Claude Code version: 2.1.5
• OS: Windows 11
• Shell: Git Bash
• Files accumulated: 119 tmpclaude-*-cwd files
• Time period: Single session (~2.5 hours)
• Location: Project working directory (not %TEMP%)
• File contents: Unix-style path (e.g., /d/repos/organization/pot/pineapple)

Timestamps show files created throughout the session (19:08-21:31) correlating with Bash tool invocations. Files persist after session ends.

This appears to be the same root cause as #8856 (missing unlinkSync after reading the temp file), with the Windows variant incorrectly placing files in CWD instead of the system temp directory.
