Bug report

• Version: 2.1.81+ 2.1.114

• Repro: launch Claude in a directory whose path contains ++ (e.g., D:\Codebase\root\dev\c++MyProject)
• Symptom: every Bash tool call fails with Working directory "..." no longer exists, but Glob/Read against the same path succeed
• Regression: worked before 2.1.81

The bash command should run, but it cannot even run ! ls, kept saying the directory does not exist while Claude is started in that the directory.
