question tool not rendering interactive UI in OpenCode Web - only displays plain text #7464

Description

What happened?

When the AI assistant invokes the question tool to ask for user input with options, OpenCode Web fails to render the interactive question UI. Instead of showing clickable options with descriptions, the interface only displays the plain text "question" without any interactive elements.

The question tool is defined in OpenCode tool schema and should render an interactive UI similar to other tools (like how bash shows command output with syntax highlighting, or how file operations show structured results). However, the Web UI appears to lack the rendering logic for this specific tool.

Steps to reproduce

1. run > opencode web
2. go to the site "http://127.0.0.1:4096/"
3. send the creation proposal with questions.
4. Trigger the AI assistant to call the question tool (for example, by asking it to create a task proposal using workflows that require user choices)
5. The AI attempts to ask a question like:

{
  "tool": "question",
  "state": {
    "status": "running",
    "input": {
      "questions": [
        {
          "multiple": false,
          "question": "合并后的新页面应该替换哪个标签页？是完全移除「收款列表」和「银行流水明细」两个标签，还是保留其中一个标签并更新其内容？",
          "header": "标签页处理",
          "options": [
            {
              "label": "移除两个标签，创建新的「银行交易仪表板」标签",
              "description": "创建全新的标签页，移除原有的两个"
            },
            {
              "description": "使用收款列表标签，重构其内容",
              "label": "保留「收款列表」标签，更新为新界面"
            },
            {
              "label": "保留「银行流水明细」标签，更新为新界面",
              "description": "使用银行流水明细标签，重构其内容"
            },
            {
              "label": "保留两个标签，只更新其中一个",
              "description": "不删除任何标签，选择其中一个更新"
            }
          ]
        }
      ]
    }
  }
}

6. Observe that only "question" text appears without any UI
