feat: sideQuery 支持第三方 provider 路由 (OpenAI/Grok/Gemini)

- 新增 getProviderPrimaryModel() 从环境变量解析 provider 主模型
- getDefaultOpus/Sonnet/HaikuModel 在第三方 provider 下回退到用户配置的主模型
- sideQuery 根据 provider 类型分发到对应的 API 适配器
- 新增 sideQueryViaOpenAICompatible (OpenAI + Grok) 和 sideQueryViaGemini 适配函数
- 避免 sideQuery 后台任务在配置第三方端点时仍请求 Anthropic API
