## 功能概述
实现跨协议模型级别的 Fallback 映射机制，允许在主 Provider 不可用时，
根据模型名称自动映射到其他协议的 Provider 和模型。
## 设计原理
- 原有 providerFallbackChain 只支持同协议内回退
- 新增 modelFallbackMapping 支持跨协议映射（如 Gemini → Claude）
- 优先级：同协议回退 > 跨协议模型映射
## 代码修改
- configs/config.json.example: 新增 modelFallbackMapping 配置示例
- src/provider-pool-manager.js: 实现跨协议映射选择逻辑
- src/service-manager.js: 传递 actualModel 参数
- src/common.js: 处理模型 fallback 后的模型名更新
- src/ui-manager.js: UI配置读写支持
- static/app/config-manager.js: 前端配置管理
- static/app/i18n.js: 中英文国际化文案
- static/index.html: 高级配置区新增配置项
## 配置示例
modelFallbackMapping: {
"gemini-claude-opus-4-5-thinking": {
"targetProviderType": "claude-kiro-oauth",
"targetModel": "claude-opus-4-5"
}
}
