[Bug Report] cd subdir persists withing processing single claude message

Bug Description

Session started in my "/Users/krzysztofwesolowski/" after experiencing claude confusion.

---
⏺ Let me test rapid sequential calls all in one message:

⏺ Bash(cd .claude && pwd && ls -1 | head -5)
⎿  /Users/krzysztofwesolowski/.claude/.claude
settings.local.json

⏺ Bash(pwd)
⎿  /Users/krzysztofwesolowski/.claude

⏺ Bash(ls -1 | head -5)
⎿  AGENT-COMMAND-MAPPING.md
agents
cache
… +2 lines (ctrl+o to expand)

⏺ Bash(pwd)
⎿  /Users/krzysztofwesolowski/.claude

⏺ Wow - you're right! The directory IS persisting in this fast scenario!
