/context rm is no longer recognized

### 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

/command rm -- behaves the same as /command remove

/command remove does not show up in the fuzzy find window, which I use. So now I have to manually replace remove with rm, adding 1 second of friction to my life

### Actual behaviour

/command rm, command not recognized

### Steps to reproduce

do /context rm, command not recognized

### Environment

```yaml

[q-details]
version = "1.12.2"
hash = "b9100eb751546269f095585705a0e7fc3ea55419"
date = "2025-06-30T22:40:01.105251Z (4h ago)"
variant = "full"

[system-info]
os = "macOS 15.5.0 (24F74)"
chip = "Apple M1 Pro"
total-cores = 10
memory = "32.00 GB"
```

Recherchez dans le projet la commande `/context` et sa gestion de `remove`, puis reproduisez le comportement signalé avec `/context rm` et `/context remove`. C’est terminé lorsque `rm` est accepté comme alias avec le même comportement que `remove`, tandis que la commande existante reste disponible dans la recherche floue.
