VSCode extension: selecting a slash command from autocomplete with Enter sends the message instead of just filling it in

What happens: When typing a /command in the VSCode extension, an autocomplete list of matching commands appears. Pressing Enter to pick a command both fills it into the input box and immediately submits the message.

What should happen: Pressing Enter on an autocomplete suggestion should only pre-fill the selected command into the input box, leaving the cursor there so I can keep typing. It should not submit.

Why it matters: Many slash commands require additional arguments/context that you supply after the command name (e.g. /review <pr-link>). Auto-submitting on selection makes the autocomplete useless for those commands, since the message fires before you can add the argument.

Environment: Claude Code VSCode extension.
