Bug: Keyboard unresponsive + infinite garbled output since v1.2.17 #16652

Description

Since version 1.2.17, OpenCode becomes mostly unresponsive after startup:

• All keyboard shortcuts fail: Tab, / commands, backspace do not work
• You can type a prompt, but cannot send it because the Enter key does not respond
• After waiting a few seconds, the screen starts printing a long string of garbled characters
• Garbled output repeats every few seconds infinitely

Affected versions

• Broken: 1.2.17 ~ 1.2.22 (all tested)
• Working: 1.2.16 and earlier

Steps to reproduce

• Upgrade or install OpenCode 1.2.17 or later
• Launch the application
• Try typing, using shortcuts, or pressing Enter to send
• Wait a moment: garbled text starts appearing repeatedly

Environment

• OS: Ubuntu 24.04.1 LTS (WSL2)
• Node.js version: v24.12.0
• zsh: 5.9 (x86_64-ubuntu-linux-gnu)
• Tabby: 1.0.230 [xterm(WebGL)]
