feat: configurable report language (default zh-CN)

Add providers.yaml `language` / Action input `language`; prompts and
published summary/inline honor it. Soften fail-closed messaging when
models 429; prefer cohere/nvidia in the first-3 parallel set for dogfood.

 | Field | Meaning |
 | --- | --- |
+| `language` | Report language for model prose + summary/inline comments (`zh-CN`, `en`, …). Alias: `report_language`. |
 | `key` | **Free-form** name of the GitHub secret / env var holding the API key. **No** required `gatekeep_` prefix. |
 | `protocol` | `openai` \| `openai-completions` \| `openai-responses` \| `anthropic` |
 | `models` | Names to use (validated against the provider’s model list API at runtime) |
 | `base_url` | Optional; known provider ids get defaults |
 
+### Report language
+
+- **This repo’s defaults:** `language: zh-CN` in `defaults/providers.yaml`.
+- **Override without editing YAML:** Action input `language: en` (or `zh-CN`).
+- Resolution order: Action input `language` → YAML `language` / `report_language` → `en`.
+- JSON field names and enums stay English; human-facing prose follows the configured language.
+
 Mix providers in one review by listing several entries. Secrets are read from the **workflow step `env`** using each entry’s `key` name.
 
 Example suggestion only (still free-form): `key: gatekeep_openrouter` is fine if you named your secret that — not required.

+- **`language`：报告语言**（本仓库默认 `zh-CN`）。也可用 Action 输入 `language:` 覆盖。别名 `report_language`。
 - **`key`：自由命名**，**不要**要求必须 `gatekeep_` 前缀（你也可以叫 `gatekeep_openrouter`，只是举例）。
 - 每个供应商只需：`key` + `protocol`（`base_url` / `models` 按需；已知 id 有默认 base_url）。
 - **不内置死模型清单**；启动时拉取供应商模型列表并校验名字。
 - 可混用多个供应商；只写你真正配置了的条目。
 
+### 如何设置语言
+
+| 方式 | 示例 |
+| --- | --- |
+| `providers.yaml` | `language: zh-CN` 或 `language: en` |
+| Action 输入（优先） | `with: { language: en }` |
+| 缺省 | 无 YAML / 无输入时回落 `en`；本仓库 defaults 已写 `zh-CN` |
+
+JSON 键名与枚举值（如 `Critical`）保持英文；摘要、结论正文、inline 评论跟人读的文案跟 `language`。
+
 ## 输入面
 
 | 项 | 含义 |
 | --- | --- |
+| `language` | 报告语言（`zh-CN` / `en` …）；覆盖 YAML |
 | `key` | Secret / 环境变量名（自由） |
 | `protocol` | `openai` / `openai-completions` / `openai-responses` / `anthropic` |
 | `models` | 参与并行审查的模型名 |
