Bug Report: Switching model in a project conversation starts a new chat outside the project
`Steps to Reproduce`
- Open a conversation inside a project in the macOS ChatGPT app.
2. Click to change the LLM model (for example, from GPT-5 to GPT-4 or any other available option).
3. The app switches you out of the project and starts a new, separate conversation.
`Expected Result`
Changing the model should keep you inside the same project and conversation context. The conversation should remain linked to the project, just using the new model.
`Actual Result`
The app kicks you out of the project and starts a new conversation in the general chat area. The project context is lost and you cannot continue your workflow inside the intended project.
