Trusted tool settings do not persist

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 15.4.0 (24E248)

### Expected behaviour

In `q chat`, when you have trusted some tools in one chat session, it should persist when quit and start a new chat.

### Actual behaviour

Trusted some tools in one chat session reset after quit and start a new chat.

### Steps to reproduce

1. Open `q chat`;
2. Trust a tool, say `some-tool`
3. Quit the chat and start a new chat;
4. `some-tool` is not trusted anymore;
