Bug with BYOK: reasoning effort not supported for model "glm-5.2:cloud"

### Describe the bug

I am experiencing an issue when using a custom BYOK configuration with Copilot CLI. Specifically, when I try to use the `--reasoning-effort max` flag, the CLI returns an error stating that the model does not support it, even though the configuration is otherwise valid.

### Affected version

v1.0.68

### Steps to reproduce the behavior

1. Run the following command:

COPILOT_PROVIDER_TYPE=openai COPILOT_PROVIDER_WIRE_API=responses COPILOT_PROVIDER_BASE_URL=https://ollama.com/v1 COPILOT_PROVIDER_API_KEY=$OLLAMA_API_KEY COPILOT_MODEL=glm-5.2:cloud COPILOT_PROVIDER_MAX_PROMPT_TOKENS=999424 COPILOT_PROVIDER_MAX_OUTPUT_TOKENS=131072 copilot --yolo --reasoning-effort max -p hi

2. Observe the error:
Error: Model "glm-5.2:cloud" does not support reasoning effort configuration (requested: "max").

### Expected behavior

The CLI should handle the reasoning effort flag gracefully or allow it for models that might support it, or at least provide a clearer error message indicating why it's not supported for this specific model configuration. Ideally, it should work as expected if the underlying API supports it.

### Additional context

I am confident I can use the command `COPILOT_PROVIDER_TYPE=openai COPILOT_PROVIDER_WIRE_API=responses COPILOT_PROVIDER_BASE_URL=https://ollama.com/v1 COPILOT_PROVIDER_API_KEY=$OLLAMA_API_KEY COPILOT_MODEL=glm-5.2:cloud COPILOT_PROVIDER_MAX_PROMPT_TOKENS=999424 COPILOT_PROVIDER_MAX_OUTPUT_TOKENS=131072 copilot --yolo --reasoning-effort max` without `-p` flag.

This issue only exists when using the `-p` flag.

首先使用列出的 BYOK 環境變數，分別執行帶有和不帶 -p 旗標的已回報命令，並比較如何到達 reasoning-effort 驗證。調查 -p 的 CLI 入口路徑以及模型能力檢查。當設定得到一致處理，或不支援的模型錯誤明確說明該限制時，即視為完成。
