Environment

• Platform (select one):

Bug Description

each time it is launched, claude launches some sort of bash command that just hangs forever

Steps to Reproduce

1. type claude, hit enter
2. use the /exit command (or ctrl-c) to exit
3. run ps -Fe
4. see yet another /bin/bash instance still hanging around

Expected Behavior

I expect claude not to leave processes laying around when exiting

Actual Behavior

There is an extra bash command still running

Additional Context

The command that is running is always something like this:
