v2.1.84: TUI rendering artifacts remain in terminal after /exit

Description

After upgrading to Claude Code v2.1.84, exiting the interactive REPL with /exit leaves TUI rendering artifacts in the terminal. The autocomplete menu text, horizontal rules, and slash command descriptions bleed into the bash prompt.

This happens on every terminal (not SSH-specific):

• Linux terminal (direct)
• Linux → SSH → remote server
• Windows PowerShell → SSH → remote server

This did not happen in previous versions.

Steps to Reproduce

1. Start claude in any terminal
2. Type /exit and press Enter
3. After Claude exits, the terminal shows leftover TUI text mixed with the bash prompt

Expected Behavior

Terminal should be clean after /exit - only the bash prompt should remain.

Actual Behavior

❯ /exitadmin@server:~$
────────────────────────────────
  /exit                                      Exit the REPL
  /extra-usage                               Configure extra usage to keep working when limits are hit
  /context                                   Visualize current context usage as a colored grid

The autocomplete dropdown content remains visible and overlaps with the shell prompt.

Workaround

Wrapping claude in a bash function with tput reset:

claude() {
    printf '\e[?1004l'
    command claude "$@"
    local exit_code=$?
    printf '\e[?1004l'
    printf '\e[0m'
    tput reset 2>/dev/null
    return $exit_code
}

This clears the screen after exit, which works but is not ideal.

Environment
