Text overlap on /exit: autocomplete renders over exit message

Description

When typing /exit in Claude Code CLI, the autocomplete/suggestion menu renders on top of the exit message text, causing visual overlap.

Steps to reproduce

1. Have a conversation in Claude Code CLI
2. Type /exit
3. Observe the exit message and the autocomplete suggestions overlapping

Screenshot

The exit message ("Resume this session with: ...") and the shell prompt overlap with the autocomplete suggestions (/context, /writing-rules, /compress, /skill-creator).

Expected behavior

The exit message should render cleanly without any autocomplete overlay. The autocomplete menu should be dismissed before the exit message is printed.

Environment

• macOS (Darwin 25.3.0)
• Terminal: macOS default Terminal
• Claude Code CLI (latest)

Additional context

The session saves correctly and --resume works fine. This is purely a visual/rendering issue where the terminal miscalculates the output height during exit, causing the autocomplete to draw over the farewell text.
