update problem says: "failed to update: `Update is only supported for "kiro-cli", the current executable is "kiro-cli-real"

### 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 6.17.0-40-generic - Linux Mint 22.3

### Expected behaviour

of couse to update kiro-cli to newer version and kiro-cli only supports --classic not --tui .

### Actual behaviour

~$ kiro-cli update
░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ 0/100error: failed to update: `Update is only supported for "kiro-cli", the current executable is "kiro-cli-real"`

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

Start by reproducing `kiro-cli update` on the reported Linux setup and trace the update path that rejects the `kiro-cli-real` executable. Confirm the fix by updating the installed kiro-cli successfully without the executable-name error.
