trusting `t` a tool doesn't work anymore

### 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 15.5.0 (24F74)

### Expected behaviour

Once trusted (`t`), `execute_bash` will run without prompt.

### Actual behaviour

It prompts every time. See log below.

### Steps to reproduce

```console
q chat "run git status 5 times in a row"
```

```
> I'll run git status 5 times in a row for you.
