Remote Control: slash command autocomplete missing and /clear doesn't clear app chat window

Description

When using Claude Code in remote-control mode (via tmux), two issues with the connected Claude app:

1. No slash command autocomplete in the remote app

Slash commands (e.g. /clear, /help, /remote-control) do not autocomplete in the Claude remote app UI. You have to type them out fully from memory.

2. /clear doesn't visually clear the app chat window

Running /clear seems to work on the CLI side, but the existing conversation content remains visible in the connected app's chat window. When running multiple tmux-ed Claude sessions, the chat history grows quickly and becomes hard to manage.

Environment

• Claude Code CLI via tmux sessions
• Remote-control mode (/remote-control)
• Multiple concurrent sessions
