[BUG] Claude Code on Windows can't execute bash when started from a directory with a ' in the path

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

In the latest version, when claude code tries to execute any bash command it gets

Bash(pwd)
  ⎿  Error: Exit code 2
     /usr/bin/bash: -c: line 1: unexpected EOF while looking for matching `''

     /usr/bin/bash: -c: line 1: unexpected EOF while looking for matching `''

When started from a directory with a ' in the path. This is new behavior; this path was working on a previous version of claude code.

This is happening in git bash, powershell, and windows terminal

What Should Happen?

Claude should handle being started from a directory with a ' in the path and should be able to execute bash commands successfully.

Steps to Reproduce

2. Navigate to that directory
3. Start claude code
4. Ask claude to execute any bash command
