### 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

Linux 6.6.87.2-microsoft-standard-WSL2 - Ubuntu 24.04.3 LTS

### Expected behaviour

Kiro-cli updates on `kiro-cli update`

### Actual behaviour

Error indicating to run doctor. Running doctor returns success. Update still results in an error.

```bash
➜ ~ q update
░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ 0/100error: failed to update: `Update is only supported for binaries installed in "/home/justirus/.local/bin", the current executable is in "/home/justirus/.toolbox/tools/kiro-cli/1.24.1"`

If this is unexpected, try running kiro-cli doctor and then try again.

➜ ~ kiro-cli doctor
