[BUG] Chat reappears after /clear when terminal is resized

What went wrong?

After running the /clear command, the chat history is cleared as expected. However, when resizing the terminal window, the previously cleared chat history reappears.

What should happen?

The chat should remain cleared after a terminal resize. The /clear command should permanently clear the conversation until a new message is sent.

Steps to reproduce

1. Start a Claude Code session
2. Have some conversation history
3. Run /clear
4. Observe that the chat is cleared
5. Resize the terminal window
6. Previous chat history reappears

Environment

• Version: 2.0.76 (Claude Code)
• OS: macOS 26.2
• Terminal: WarpTerminal
• Platform: Anthropic API
• Model: Opus

Is this a regression?

Yes - this behavior was not present in earlier versions.
