[Bug] Opencode should use config's `name` instead of `id` when using siliconflow-cn.

[Jostar1024]

Description

https://github.com/sst/opencode/issues/5615 After the above issue we can fetch the siliconflow-cn's model but cannot use it.

To make siliconflow-cn works with opencode, it should use the name in the config instead of id.

OpenCode version

1.0.207

Steps to reproduce

For example, I tested it with deepseek-ai/DeepSeek-V3.2-Exp. It returns Bad Request: Model does not exist. Please check it carefully.

I checked the data in ~/.local/share/opencode/storage/message/ses_491b34852ffeUXhAHgQZeQ6iLm/, the output are the following.

// request
{
  "id": "msg_b6e4cb7af001mvoKGrBM0hQ8F4",
  "sessionID": "ses_491b34852ffeUXhAHgQZeQ6iLm",

  "model": {
    "providerID": "siliconflow-cn",
    "modelID": "deepseek-ai-deepseek-v3.2-exp"
  }
}
// response
{
  "id": "msg_b6e4cb7b7001R6QFm74Sy9ood0",
  "sessionID": "ses_491b34852ffeUXhAHgQZeQ6iLm",

    "completed": 1767082080453
  },
  "error": {
    "name": "APIError",
    "data": {
      "message": "Bad Request: Model does not exist. Please check it carefully.",
      "statusCode": 400,
      "isRetryable": false,
      "responseHeaders": {
        "connection": "keep-alive",
        "content-length": "87",
        "content-type": "application/json; charset=utf-8",
        "date": "Tue, 30 Dec 2025 08:08:00 GMT",
        "x-siliconcloud-trace-id": "ti_zhibn3p1k2bfikoist"
      },
      "responseBody": "{\"code\":20012,\"message\":\"Model does not exist. Please check it carefully.\",\"data\":null}"
    }
  },
  "parentID": "msg_b6e4cb7af001mvoKGrBM0hQ8F4",
  "modelID": "deepseek-ai-deepseek-v3.2-exp",
  "providerID": "siliconflow-cn",
  "mode": "build",
  "agent": "build",
  "path": {
    "cwd": "/Users/yucheng/.config/mpv",
    "root": "/"
  },
  "cost": 0,
  "tokens": {
    "input": 0,
    "output": 0,
    "reasoning": 0,
    "cache": {
      "read": 0,
      "write": 0
    }
  }
}

After I changed the model's ID to its name in ~/.cache/opencode/models.json, opencode returns the correct result.
