[Bug] Config save not triggered on Enter key press

Bug Description

Enter to save on the config doesn't really save.

To reproduce

• Start claude
• /config
• search something like vim
• pressing enter cycles the value as if you pressed space.

If you esc now, the value change is dismissed. You have to leave the config without pressing esc for the change to be persisted. This is quite unintuitive.
