Feature request: For prompts using /editor, they will not appear in the prompt history.

### 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 15.6.1 (24G90)

### Expected behaviour

After entering a prompt using the `/editor` command, it would be nice if the prompts contents entered via `/editor` could also be retrieved using the arrow keys.

### Actual behaviour

Only "/editor" is displayed instead of the actual prompt content entered through the editor

### Steps to reproduce

## Steps to Reproduce

1. Enter the `/editor` command
2. Write and save a prompt in the editor
3. After Claude’s response finishes, press the up arrow (⬆️) key to check the previous prompt content
