[Bug] Unexpected Model Switching Between Terminal Sessions

Bug Description
I had claude open in one terminal tab (in ghostty), on macOS; I was running a task with Sonnet 4. I started claude in another terminal (in VSCode); I was running a task with Opus 4.1. I go back to the first terminal tab, and I see that in Claude's response to me, it was waiting on a permission prompt to proceed. and when I approved it, I noticed the model in my statusline has changed from Sonnet to Opus. this has happened several times in the past week or so, possibly always (?). thank you for your help resolving this. and thank you for building such a wonderful product.
