feat: add Chinese UI, Responses models, and mirrored Windows setup

Localize the web console and persist custom model and capability settings.
Use OpenAI Responses exclusively and move runtime limits into environment configuration.
Bootstrap uv and the virtual environment on Windows, support optional China mirrors,
and package source distributions without environments, build output, or credentials.

Update regression tests and repository quality checks for the new behavior.

+### Model and feature settings
+
+The web console now uses Simplified Chinese. Open **系统设置与运行准备 → 模型配置** to edit and save the Responses base URL, model, API key, request timeout, and retry count. **测试连接** tests the current form without saving; **保存配置** persists it to `.env`. Leave the key blank to retain the existing credential. Existing keys are never returned to the browser.
+
+All models use **OpenAI Responses**, including custom gateways. Set `OPENAI_API_KEY`, `OPENAI_BASE_URL` (the API root, usually ending in `/v1`), and `OPENAI_MODEL` (for example `mimo-v2.6-flash`). Gemini, Anthropic and Chat Completions transports are no longer supported. Video analysis sends sampled image frames and requires image input support. Structured output uses Responses function calling with local schema validation.
+
+The **功能开关** section persists video analysis/recording, final reports, and Flash step summaries. Changes apply to new tasks and survive restart. Environment variables take precedence over `.env`; explicit per-node or task overrides take precedence over global defaults. See [`.env.example`](.env.example) for timeout settings and the [Chinese setup guide](README_CN.md#网页模型配置与功能开关) for details.
