/clear command hangs when connected via remote control from iOS app

Description

When connected to Claude Code via remote control from an iOS app, running /clear hangs indefinitely even though the command successfully clears the conversation. The user must press Stop to regain control.

On the local machine, the clear completes successfully — the hang only manifests on the iOS remote control side.

Steps to Reproduce

1. Connect to Claude Code via remote control from an iOS app
2. Have a conversation with some history
3. Run /clear
4. Observe that the iOS app hangs / never shows completion
5. Press Stop — conversation is actually cleared on the local machine

Expected Behavior

/clear should complete and return control to the user promptly on the iOS remote control client, matching the behavior seen on the local machine.

Actual Behavior

The clear succeeds on the local machine, but the iOS remote control client never receives the completion signal and hangs until the user presses Stop.

Environment

• Platform: macOS (Darwin 25.4.0)
• Remote control client: iOS app
