fix(dashscope-image-gen): 默认模型改为 gpt-image-2 v1.4.0 (#29)

## Summary 上游 proxy (desirecore-cloud at api.yizhioa.cn) 仅支持 `gpt-image-2` 图片生成模型，`wan2.7-image` 返回 `model_price_error`。 The upstream proxy (desirecore-cloud) only supports `gpt-image-2` for image generation. `wan2.7-image` returns `model_price_error`. ### Changes - Default model changed from `wan2.7-image` → `gpt-image-2` - `wan2.7-image` / `wan2.7-image-pro` kept as optional (requires user-configured DashScope provider) - Added auto-fallback strategy: `model_price_error` → retry with `gpt-image-2` - Size values adapted for gpt-image-2: `1536x1024` / `1024x1536` - Skill display name updated: 阿里云文生图 → AI 文生图 - Market version: 1.2.4 → 1.2.5, skill version: 1.3.0 → 1.4.0 ### Test - `gpt-image-2` via `/images/generations` endpoint: verified working (b64_json response, 1.5MB PNG) - Upload to media-store: verified working - `dc-media://` rendering: verified working

 ## Provider & Default Compute

-This skill uses Alibaba Cloud DashScope's Wan (通义万相) models. You do NOT need to specify a provider — just pass `"serviceType": "image_gen"` and the system will automatically route to the correct provider:
-
- **DesireCore Cloud** (default, always available): The built-in compute provider already supports `image_gen` with Wan models. Users can generate images immediately without any configuration.
- **DashScope** (user-configured): If the user has configured their own DashScope API key, the system may route to it.
+You do NOT need to specify a provider — just pass `"serviceType": "image_gen"` and the system will automatically route to the correct provider.

 **Never** try to query provider lists, read compute.json, or explore available models through API calls. The models listed below are guaranteed to work.

 ## Model Selection

 | Model | Characteristics | When to use |
-|------|------|---------|
-| wan2.7-image-pro | Flagship, 4K resolution, thinking_mode | User asks for top quality, 4K, or rich detail |
-| wan2.7-image | Standard high quality, thinking_mode | **Default**, for unspecified requests |
+|-------|----------------|-------------|
+| gpt-image-2 | High quality, fast, versatile styles | **Default** — use when user does not specify a model |
+| wan2.7-image | Standard high quality (requires DashScope provider) | Only when user explicitly asks for Wan / DashScope |
+| wan2.7-image-pro | Flagship, 4K resolution (requires DashScope provider) | Only when user explicitly asks for top quality Wan model |

-**Default rule**: if the user does not specify a model, use `wan2.7-image`.

+
+**Note**: `wan2.7-image` and `wan2.7-image-pro` only work when the user has configured their own Alibaba Cloud DashScope provider. If you get an error with these models, fall back to `gpt-image-2`.

-The system prompt already contains the agent-service API address under "本机 API" (e.g. `Agent Service: https://127.0.0.1:61000`). Extract the URL from there and use it directly.
