No space left on device

### 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 15.7.2 (24G313)

### Expected behaviour

There is a slew of development pipelines that are in my terminal that I have not authorized. I would love to design applications for apple possibly, but I am not and have never been comfortable with them taking every bit of storage only when I want to install something not related to either apple or their developers

### Actual behaviour

slipstream3@Erics-Mac-mini ~ % q update
████████████████████████████████████████████████████████████████████████ 100/100error: failed to update: `ditto: /private/var/folders/2p/32l4qnk15kg__pfjynhqdb_40000gn/T/q-downloadk4qm2a/Kiro CLI.app/Contents/MacOS/kiro-cli-chat: No space left on device

----as you can see there was 100% downloaded. Should I just download Kiro from their hugging face or open source (this is a china model that is extremely impressive with Claude Code and cli coding.

### Steps to reproduce

Any time I want to download something not aligned with Apple it seems I "magically have no HD space" while I have only owned this MacMini for a few months. Quite interesting if you ask me. I was never asked about any of this and do not like the idea of another company determining what I can/cannot update in my terminal. What happened to them?

Inizia con il fallimento segnalato di `q update` su macOS e riproducilo dopo aver eseguito `q doctor` e `q restart`. Il payload non indica file sorgente né test, quindi individua prima il percorso di aggiornamento e la gestione dell’output di `ditto` “No space left on device”; done deve includere un comportamento chiaramente definito e verificato per questo fallimento.
