Disabling autocomplete does not work for specific commands

### 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 15.3.1 (24D70)

### Expected behaviour

Q CLI should adhere to the setting ```autocomplete.disableForCommands = ["cd"]``` and shouldn't allow cd to autocomplete on.

### Actual behaviour


The above image show the setting for autocomplete. But in terminal the autocomplete works overriding the setting.

### Steps to reproduce

_No response_

Inizia riproducendo il problema in Q CLI su macOS con `autocomplete.disableForCommands = ["cd"]`, dopo aver eseguito `q doctor` e `q restart` come descritto. Traccia la gestione dell’autocompletamento per le esclusioni specifiche dei comandi e verifica che `cd` non venga più completato automaticamente quando l’impostazione è abilitata.
