[FEATURE] After user executes a slash command, restore the previous Prompt Suggestion

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Suppose I am at the prompt, and there is a prompt suggestion in light gray. At that point, if I do /copy (to copy the previous response to the clipboard), then the prompt suggestion is no longer there. It would be helpful to still have it there.

Proposed Solution

If I do a slash command such as /copy, then when it eventually returns to the prompt, that previously suggested prompt is no longer there. It would be helpful if it was still there.

Use Case Example

1. Tell Claude Code to do something
2. It does it, and then it displays a bunch of helpful info, e.g. what it did and next steps
3. Also, after the ❯ prompt, there is a lightgray prompt suggestion
4. Type /copy
5. Claude Code copies the previous response to the clipboard
6. Now the ❯ prompt no longer has a prompt suggestion after it
