[BUG] Slash command menu remnants persist in terminal after /exit

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

After exiting Claude Code with /exit, the slash command autocomplete menu (showing /extra-usage, /context, /memory, /vim, /clear) remains rendered in the terminal. The menu visually overlaps with the shell prompt, appearing as a display artifact that doesn't clear on its own.

What Should Happen?

The terminal should be fully restored to a clean state after exiting Claude Code via /exit. No UI elements (such as the slash command autocomplete menu) should remain rendered on screen.
