What's Wrong?

Description:
When the Bash tool's internal working directory is deleted (e.g., during file reorganization), all subsequent bash commands fail with exit
code 1 and no output. The shell becomes completely non-functional until the deleted directory is recreated.

Steps to reproduce:

1. Run cd /some/subdirectory via Bash tool
2. Delete that directory (via rmdir or file moves)
3. Try any bash command - even echo test or ls /
4. All commands fail with exit code 1, no error message

Expected behavior:

• Shell should fall back to a valid directory (e.g., project root)
• Or provide a clear error message about invalid CWD

Actual behavior:

• Silent failure on all commands
• No indication of what's wrong
• Only fix is recreating the deleted directory

Workaround:
Recreate the deleted directory, then cd to a valid location.

What Should Happen?

Expected behavior:

Shell should fall back to a valid directory (e.g., project root)
