Switch to VectorEngine gpt-image-2 and edits

Replace uses of the legacy `gpt-image-2-all` model with `gpt-image-2` and standardize image workflows: no-reference generation uses POST /v1/images/generations, any-reference flows use POST /v1/images/edits with multipart `image` parts. Update SKILLs, generation scripts, decision logs, and docs to reflect the contract change and edits-vs-generations guidance. Apply corresponding changes across backend (api-server match3d/puzzle modules, openai image adapter, mappers, telemetry, spacetime client/module), frontend components and services (Match3D, Puzzle, CreativeImageInputPanel, runtime shells), and add new spritesheet/parser files and tests. Also add media/logo.png. These changes align repository code and documentation with the VectorEngine image API contract and update generation/upload handling (green-screen -> alpha processing, spritesheet handling, and related tests).

素材使用 VectorEngine `gpt-image-2-all` / image-2 生成。图片生成只能走后端接口,前端不得读取、拼接或暴露 `VECTOR_ENGINE_API_KEY`

为降低生成成本,创作提交后只生成两张原始图片:一张 `2x2` 素材 sheet 和一张单独场景背景图。`2x2` 素材 sheet 固定包含左上物品 A、右上物品 B、左下篮子、右下礼物盒。服务端必须按固定格切图并把物品、篮子和礼物盒转成透明 PNG。只有透明抠图后的两个物品素材才允许写入草稿 `itemAssets` 并进入游戏运行态。左右手位置指示器属于运行态默认规则,使用项目内置静态素材,不在每次创作时生成。
