[BUG] Interactive response prompt freezes intermittently on Confirm or Esc

###-Description:
When an agent generates a question prompt with selectable choices, the UI intermittently freezes. Clicking the Confirm button does not submit the selected response, and pressing the Esc key fails to dismiss or cancel the prompt.

###-Environment:
OpenCode Version: 1.18.29
OS: Windows 11
Interface: Terminal UI

###-Steps to Reproduce:
1)Trigger an agent action that results in an interactive question prompt with selectable options.
2)Select a response from the available choices.
3)Attempt to submit the choice by clicking Confirm, or attempt to cancel by pressing Esc.
4)Observe that the prompt occasionally becomes unresponsive and ignores both inputs.

###-Expected Behavior:
Clicking Confirm should immediately submit the chosen response and proceed with the agent's workflow. Pressing Esc should consistently dismiss the prompt and cleanly cancel the interaction.

###-Actual Behavior:
The prompt occasionally freezes, ignoring both Confirm clicks and Esc key presses, effectively blocking the agent workflow.

###-Frequency:
Intermittent (occurs sometimes, but not consistently on every prompt).

###-Additional Notes:
I am interested in contributing to OpenCode and would like to work on fixing this bug. Any initial guidance or pointers to the relevant UI event handlers or state logic managing these interactive prompts would be highly appreciated
