TUI crashes when resizing terminal window (Windows / CMD)

[CodeNewbie88]

Description

To Reproduce

Steps to reproduce the behavior:

1. Open Command Prompt (CMD) on Windows，run opencode

2. Start OpenCode TUI

3. While the TUI is running, resize the CMD window (drag to change width or height)，The application crashes immediately.

Expected behavior

The TUI should handle terminal resize events gracefully and continue running, with the layout reflowing or redrawing correctly.
