+# Vue Composable 架构重构计划
+
+## 1. 背景与问题
+
+在对核心服务进行“去单例化”重构后，应用启动时暴露出一系列与 Vue 响应式系统和组件通信相关的严重问题。这些问题起初表现为多种警告和错误：
+
+1.  **属性类型不匹配**: 子组件收到的 props 类型与预期不符，例如期望 `Boolean` 却收到了 `Object` (`[Vue warn]: Invalid prop: type check failed`)。此问题在 `PromptPanel` 等多个组件中普遍存在。
+2.  **无效的侦听源**: `useStorage` 等 Composable 因其依赖的 `services` 对象尚未初始化，导致 `watch` 侦听了一个 `undefined` 源 (`[Vue warn]: Invalid watch source: undefined`)。
+3.  **顶层调用错误**: 在某些异步初始化逻辑中尝试调用 Composable，导致 Vue 抛出 `Must be called at the top of a 'setup' function` 错误。
+
+## 2. 根本原因分析
+
+经过排查，这些看似分散的问题，都指向同一个系统性的架构缺陷：**Composable 的状态封装模式不当**。
+
+许多业务逻辑 Composable（如 `usePromptOptimizer`, `useModelManager`）返回的是一个包含了多个 `ref` 的普通 JavaScript 对象，形如：
+
+```typescript
+// 旧模式
+function usePromptOptimizer() {
+  const isIterating = ref(false);
+  const someOtherState = ref('');
+  return { isIterating, someOtherState }; 
+}
+```
+
+当在 `App.vue` 中使用时：
+
+```html
+<!-- App.vue -->
+<script setup>
+const optimizer = usePromptOptimizer();
+</script>
+
+<template>
+  <!-- 
+    问题所在：optimizer.isIterating 是一个 ref 对象，
+    而不是它内部的值。Vue 的模板自动解包不会深入到对象的属性。
+  -->
+  <PromptPanel :is-iterating="optimizer.isIterating" />
+</template>
+```
+
+`PromptPanel` 组件收到的 `is-iterating` prop 是一个 `Ref<boolean>` 对象，而非期望的 `boolean` 值，导致类型检查失败。这个问题是所有连锁反应的核心。
+
+## 3. 解决方案：统一返回 `reactive` 对象
+
+为了从根本上解决问题，我们采取了统一的架构决策：**重构所有核心业务 Composable，使其返回一个单一的 `reactive` 对象**。
+
+```typescript
+// ✅ 新模式
+function usePromptOptimizer() {
+  const state = reactive({
+    isIterating: false,
+    someOtherState: '',
+  });
+  
+  // ... 逻辑代码修改 state ...
+
+  return state; // 返回一个响应式对象
+}
+```
+
+当在 `App.vue` 中使用时，问题迎刃而解：
+
+```html
+<!-- App.vue (修改后) -->
+<script setup>
+const optimizerState = usePromptOptimizer();
+</script>
+
+<template>
+  <!-- 
+    现在 optimizerState.isIterating 直接是 boolean 值，
+    符合子组件的 prop 预期。
+  -->
+  <PromptPanel :is-iterating="optimizerState.isIterating" />
+</template>
+```
+
+这个模式确保了传递给子组件的是原始值，而不是 `ref` 包装器，同时保留了跨组件的状态响应性。
+
+## 4. 实施过程与成果 (已完成) ✅
+
+本次重构已**圆满完成**。
+
+**核心重构**:
+- [x] **`usePromptOptimizer`**: 已重构为返回 `reactive` 对象。
+- [x] **`useModelManager`**: 已重构为返回 `reactive` 对象。
+- [x] **`useHistoryManager`**: 已重构为返回 `reactive` 对象。
+- [x] **`useTemplateManager`**: 已重构为返回 `reactive` 对象。
+- [x] **`usePromptTester`**: 已重构为返回 `reactive` 对象。
+- [x] **`useModals`**: 已重构为返回 `reactive` 对象。
+
+**辅助修复**:
+- [x] **修复 `useStorage`**: `ThemeToggleUI` 和 `LanguageSwitch` 组件被修改为通过 `inject` 获取 `services` 实例，并将其传递给 `useStorage`，解决了依赖过早初始化的问题。
+- [x] **适配 `App.vue`**: 调整了 `App.vue` 中的模板绑定和 `computed` 属性，以适应新的 `reactive` 状态结构，并修复了因此产生的类型错误。
+- [x] **依赖注入**: 在 `ModelSelect` 和 `DataManager` 等组件中，推广了使用 `inject` 直接从 `services` 中获取依赖的模式，简化了 `App.vue` 的模板。
+
+**最终成果**:
+- 彻底解决了启动时的所有 Vue `warn` 和 `error`。
+- 建立了一套更健壮、更可预测、更符合 Vue 最佳实践的状态管理范式。
+- 应用代码，特别是 `App.vue`，变得更加简洁和易于维护。
+
+## 5. 经验总结
+
+- **`reactive` vs. 对象包裹的 `ref`**: 对于一组高度内聚、会被一同传递或操作的响应式状态，使用 `reactive` 封装是比返回一个包含多个 `ref` 的对象更优的模式。它能有效避免深层解包问题，并简化消费端的代码。
+- **`provide`/`inject` 是服务注入的利器**: 对于全局性或跨层级的服务/依赖（如 `services` 对象），使用 `provide`/`inject` 是比层层传递 `props` 更优雅、更高效的解决方案。
+- **系统性问题需要系统性解决方案**: 面对一系列看似不同的报错，深入分析其共性根源至关重要。本次通过识别核心的“状态封装模式”问题，一次性解决了所有表层症状。

+## 8. Vue Composable 架构重构：解决异步初始化问题
+
+### 问题背景
+在异步回调中调用Vue Composable函数会导致错误：`Uncaught (in promise) SyntaxError: Must be called at the top of a 'setup' function`。这违反了Vue Composition API的核心规则，需要重构架构。
+
+### 核心解决方案：顶层声明，响应式连接，内部自治
+```typescript
+// ❌ 错误：在异步回调中调用Composable
+onMounted(async () => {
+  const services = await initServices();
+  const modelManager = useModelManager(); // 错误：不在setup顶层调用
+});
+
+// ✅ 正确：顶层声明，响应式连接
+const { services } = useAppInitializer(); // 在顶层调用
+const modelManager = useModelManager(services); // 在顶层调用，传入services引用
+
+// 内部实现：响应式连接
+export function useModelManager(services: Ref<AppServices | null>) {
+  // 状态定义...
+  
+  // 响应式连接：监听服务就绪
+  watch(services, (newServices) => {
+    if (!newServices) return;
+    // 使用已就绪的服务...
+  }, { immediate: true });
+  
+  return { /* 返回状态和方法 */ };
+}
+```
+
+### 架构设计要点
+1. **统一服务接口**：创建`AppServices`接口，统一管理所有核心服务
+   ```typescript
+   // packages/ui/src/types/services.ts
+   export interface AppServices {
+     storageProvider: IStorageProvider;
+     modelManager: IModelManager;
+     templateManager: ITemplateManager;
+     historyManager: IHistoryManager;
+     dataManager: DataManager;
+     llmService: ILLMService;
+     promptService: IPromptService;
+   }
+   ```
+
+2. **服务初始化器**：`useAppInitializer`负责创建和初始化所有服务
+   ```typescript
+   // 返回带有错误处理的服务引用
+   export function useAppInitializer() {
+     const services = ref<AppServices | null>(null);
+     const isInitializing = ref(true);
+     const error = ref<Error | null>(null);
+     
+     onMounted(async () => {
+       try {
+         // 初始化服务...
+         services.value = { /* 服务实例 */ };
+       } catch (err) {
+         error.value = err instanceof Error ? err : new Error(String(err));
+       } finally {
+         isInitializing.value = false;
+       }
+     });
+     
+     return { services, isInitializing, error };
+   }
+   ```
+
+3. **Composable参数模式**：所有Composable接收`services`引用作为参数
+   ```typescript
+   export function useModelManager(services: Ref<AppServices | null>) {
+     // ...
+   }
+   
+   export function useTemplateManager(services: Ref<AppServices | null>) {
+     // ...
+   }
+   ```
+
+### 关键经验
+1. **Vue响应式上下文**: Vue Composable必须在`<script setup>`顶层同步调用，异步回调中调用会导致错误
+2. **响应式连接模式**: 使用`watch`监听服务就绪，而不是在回调中调用Composable
+3. **快速失败原则**: 在开发环境中，快速暴露问题比隐藏问题更有价值，有助于及早发现和修复问题
+4. **统一架构**: 保持所有Composable的一致架构模式，有助于代码理解和维护
+5. **类型系统挑战**: 复杂的类型系统可能导致接口不匹配问题，需要仔细处理类型定义和实现
+
+### 实施建议
+- 所有Composable在`<script setup>`顶层调用
+- 使用`watch`监听服务就绪，而不是在回调中调用Composable
+- 使用TypeScript非空断言操作符`!`快速暴露潜在问题
+- 统一服务接口和参数模式，提高代码一致性
+- 详细记录架构决策和经验，便于团队知识传承
+
+### 7. Composable 重构：`reactive` vs `ref` 的深度实践 (2024-07-28)
+
+**背景**: 为解决 Vue 深层嵌套 `ref` 无法自动解包的问题，我们将多个核心 Composables（如 `usePromptOptimizer`）的返回值从包含多个 `ref` 的对象，重构为了单一的 `reactive` 对象。此举虽然简化了顶层状态管理，但引发了一系列复杂的联动错误。
+
+**核心挑战与解决方案**:
+
+1.  **依赖注入失败 (`templateLanguageService`)**
+    *   **现象**: `BuiltinTemplateLanguageSwitch` 组件无法通过 `inject` 获取 `templateLanguageService` 实例，导致初始化失败。
+    *   **根因**: `useAppInitializer.ts` 在初始化服务时，虽然创建了 `languageService`，但**没有将其添加到最终提供给整个应用的 `services` 对象中**。
+    *   **修复步骤**:
+        1.  修改 `useAppInitializer.ts`，将 `templateLanguageService` 添加到返回的 `services` 对象中。
+        2.  修改 `packages/ui/src/types/services.ts`，在 `AppServices` 接口中添加 `templateLanguageService: TemplateLanguageService` 类型定义，解决 TypeScript 报错。
+    *   **教训**: 依赖注入的链条必须完整。服务不仅要被创建，还要被正确地"注册"和"提供"。
+
+2.  **响应式接口不匹配 (`reactive` -> `ref`)**
+    *   **现象**: `useTemplateManager` 中出现 `Cannot read properties of null (reading 'value')` 错误。
+    *   **根因**: `useTemplateManager` 期望接收一个 `ref` 类型的参数 (`selectedTemplate`)，以便能通过 `.value` 进行双向绑定。而重构后的 `App.vue` 直接传递了 `optimizer.selectedOptimizeTemplate`，这是一个普通值，而非 `ref`。
+    *   **优雅的解决方案**: 使用 `toRef` 作为"适配器"。
+        ```typescript
+        // App.vue
+        import { toRef } from 'vue';
+
+        const optimizer = usePromptOptimizer(...);
+        
+        // 为 reactive 对象的属性创建一个双向绑定的 ref
+        const selectedOptimizeTemplateRef = toRef(optimizer, 'selectedOptimizeTemplate');
+
+        const templateManager = useTemplateManager({
+            // 将创建的 ref 传入，满足 useTemplateManager 的接口期望
+            selectedTemplate: selectedOptimizeTemplateRef,
+            // ...
+        });
+        ```
+    *   **教训**: 在 Composable 之间传递响应式状态时，必须注意"接口"匹配。`toRef` 是连接 `reactive` 对象和期望 `ref` 的旧代码或子模块的完美桥梁。
+
+3.  **健壮性修复 (Vercel API 检测)**
+    *   **现象**: 控制台出现 `Vercel API detection failed SyntaxError: Unexpected token '<'` 警告。
+    *   **根因**: `environment.ts` 中的检测函数在服务端返回 HTML 错误页面（而非 JSON）时，依然尝试调用 `response.json()`，导致解析失败。
+    *   **修复**: 在解析前增加 `Content-Type` 响应头检查，确保只在内容为 `application/json` 时才执行解析。
+    *   **教训**: 所有与外部 API 的交互都应假定可能失败。在解析响应前，务必检查其内容类型和状态码。
+
+**总结**: 本次重构深刻揭示了 Vue 3 响应式系统的几个关键点：
+- `reactive` 适用于管理**一组**相关状态，简化顶层 API。
+- `ref` 依然是跨组件或 Composable 边界传递**单个**响应式变量的可靠方式。
+- `toRef` 和 `toRefs` 是在 `reactive` 和 `ref` 之间无缝切换、适配新旧代码的必备工具。
+- 依赖注入和服务初始化流程的正确性，是复杂应用稳定运行的基石。

+## 任务：Vue Composable 架构重构 - 2025-07-05
+
+### 目标
+解决在异步回调中调用 Vue Composable 函数导致的错误：`Uncaught (in promise) SyntaxError: Must be called at the top of a 'setup' function`。重构所有 Composable 文件，实现"顶层声明，响应式连接，内部自治"的设计模式。
+
+### 计划步骤
+[x] 1. **创建统一的服务接口定义**
+    - 完成时间：2025-07-05 上午
+    - 实际结果：成功创建 `packages/ui/src/types/services.ts` 文件，定义 `AppServices` 接口
+    - 经验总结：中心化类型定义提高了代码一致性和可维护性
+
+[x] 2. **重构核心 Composable 文件**
+    - 完成时间：2025-07-05 下午
+    - 实际结果：成功重构 8 个主要 Composable 文件，使其接收 `services: Ref<AppServices | null>` 参数
+    - 经验总结：统一的参数模式使代码更加一致，易于理解
+
+[x] 3. **更新 useAppInitializer**
+    - 完成时间：2025-07-05 晚上
+    - 实际结果：增强了错误处理和日志记录，添加了 `error` 状态
+    - 经验总结：良好的错误处理对调试至关重要
+
+[x] 4. **更新 useModals**
+    - 完成时间：2025-07-05 晚上
+    - 实际结果：将 useModals 也纳入新架构，接收 services 参数
+    - 经验总结：保持架构一致性对于长期维护非常重要
+
+[x] 5. **更新文档**
+    - 完成时间：2025-07-05 晚上
+    - 实际结果：更新了 `docs/composables-refactor-plan.md` 和 `docs/experience.md`
+    - 经验总结：及时记录架构决策和经验对团队知识传承很重要
+
+[ ] 6. **更新 App.vue**
+    - 进行中：2025-07-06
+    - 当前状态：遇到类型错误，需要进一步解决
+    - 问题记录：
+      - `services` 对象与 `AppServices` 接口不匹配，特别是 `dataManager` 属性
+      - 尝试使用类型断言 `as any` 临时解决，但仍有类型错误
+      - 需要进一步研究 `DataManager` 类型定义和实现
+
+### 问题记录
+1. **Vue Composable 调用时机问题**
+   - 原因：Vue 要求 Composable 函数必须在 `<script setup>` 顶层同步调用，而非在异步回调中
+   - 解决方案：将 Composable 调用提升到顶层，通过 `watch(services, ...)` 响应服务就绪
+   - 经验总结：理解 Vue 的响应式上下文机制对于正确使用 Composition API 至关重要
+
+2. **防御性编程 vs 快速失败**
+   - 原因：团队对安全检查（如 `if (!modelManager.value) return`）的处理有不同意见
+   - 解决方案：经讨论后采用"快速失败"模式，使用 TypeScript 非空断言操作符 `!`
+   - 经验总结：架构决策应考虑团队偏好和项目特性，在此情况下快速暴露问题比隐藏问题更有价值
+
+3. **App.vue 类型错误**
+   - 原因：`services` 对象与 `AppServices` 接口定义不匹配，特别是 `dataManager` 属性
+   - 临时解决方案：使用 TypeScript 类型断言 `as any` 绕过类型检查
+   - 后续计划：
+     - 检查 `DataManager` 类型定义和实现
+     - 确保 `useAppInitializer` 返回的对象符合 `AppServices` 接口
+     - 可能需要调整 `AppServices` 接口或服务实现
+
+### 里程碑

+
+### 下一步建议
+
+1. **解决 App.vue 类型错误**：
+   - 深入研究 `DataManager` 类型定义和实现
+   - 检查 `useAppInitializer` 返回的对象结构
+   - 可能需要调整 `AppServices` 接口或服务实现
+   - 考虑创建适配器或类型转换函数
+
+2. **添加错误处理UI**：
+   - 利用 `useAppInitializer` 返回的 `error` 状态

+
+### 核心经验总结
+
+1. **Vue 响应式上下文**: Vue Composable 必须在 `<script setup>` 顶层同步调用，异步回调中调用会导致错误
+2. **响应式连接模式**: 使用 `watch(services, ...)` 模式处理服务的异步初始化，保持代码清晰和可维护
+3. **快速失败原则**: 在开发环境中，快速暴露问题比隐藏问题更有价值，有助于及早发现和修复问题
+4. **统一架构**: 保持所有 Composable 的一致架构模式，有助于代码理解和维护
+5. **类型系统挑战**: 复杂的类型系统可能导致接口不匹配问题，需要仔细处理类型定义和实现
+
+**任务状态：⚠️ 部分完成，需要解决类型错误**

+## 任务：架构重构：切换到高层服务代理IPC模型 - 2024-07-25
+### 目标
+解决当前底层 `fetch` 代理方案因模拟不完善导致的脆弱性和兼容性问题。建立一个稳定、可维护、职责清晰的桌面端应用架构，将主进程作为后端服务提供者，渲染进程作为纯粹的前端消费者。
+
+### 计划步骤
+- [ ] 1. **清理 `core` 包**: 移除所有特定于 Electron 的逻辑（如 `isRunningInElectron` 和 `fetch` 注入），使其回归为一个纯粹、平台无关的核心业务逻辑库。
+- [ ] 2. **改造 `main.js`**: 使其成为服务提供者，通过 `require('@prompt-optimizer/core')` 直接消费 `core` 包，并在主进程中实例化 `LLMService` 等核心服务。
+- [ ] 3. **实现主进程存储方案**: 为 `main.js` 中的服务提供一个适合 Node.js 环境的存储方案。第一阶段先实现一个临时的 `MemoryStorageProvider`。
+- [ ] 4. **重构 IPC 通信协议**: 废弃底层的 `api-fetch` 代理，在 `main.js` 和 `preload.js` 中建立基于 `ILLMService` 公共方法（如 `testConnection`, `sendMessageStream`）的高层 IPC 接口。
+- [ ] 5. **创建渲染进程代理**: 在 `core` 包中创建一个 `ElectronLLMProxy` 类，该类实现 `ILLMService` 接口，其内部方法通过 `window.electronAPI.llm.*` 调用 IPC 接口。
+- [ ] 6. **改造服务初始化逻辑**: 修改 `useServiceInitializer.ts`，使其能够根据当前环境（Web 或 Electron）判断，为应用提供真实的 `LLMService` 实例或 `ElectronLLMProxy` 代理实例。
+
+### 问题记录
+1. 底层`fetch`代理导致`AbortSignal`、`Headers`等对象在跨IPC传输时出现序列化和实例类型不匹配的问题，导致应用崩溃且难以维护。
+   - 原因：试图模拟一个复杂且不稳定的底层Web API，违反了关注点分离原则。
+   - 解决方案：切换到代理我们自己定义的高层、稳定的服务接口。
+   - 经验总结：跨进程通信应基于稳定、简单、可序列化的数据结构和接口，避免代理复杂的底层原生对象。

+### 5.4 UI 层的连锁反应与应对
+
+- **发现**: 核心服务的"去单例化"重构，对上层 UI 和 Composable 的冲击比预期更大。原先直接导入单例的模式被破坏后，引发了包括`属性类型检查失败`、`响应式状态丢失`和`服务未初始化`在内的一系列连锁问题。
+- **应对**: 我们为此制定了专门的 [`composables-refactor-plan.md`](./composables-refactor-plan.md) 和 [`web-refactor-plan.md`](./web-refactor-plan.md)。核心对策是：1) 将返回多个 `ref` 的 Composable 重构为返回单个 `reactive` 对象，以解决属性传递问题。2) 在组件层级，通过 `provide/inject` 机制注入服务，减少了属性钻孔 (`props drilling`)。这次经历表明，底层架构的重大变更，必须伴随对上层应用影响的充分评估和细致的改造计划。

+    - [x] **包裹**: 在模板的根元素上使用 `v-if="!isInitializing"`，并添加一个 `v-else` 的加载状态。
+    - [x] **传递**: 将 `services.value` 作为 props 传递给需要的子组件，或在 `composable` 中使用 `services.value.modelManager` 等。
+    - [x] **清理**: 删除 `onMounted` 中手动的初始化逻辑。

+# Web 与插件端架构重构计划
+
+## 1. 当前状态与问题
+
+**最新状态 (2024-12-29):** 底层与上层应用重构均已完成。
+
+- **已完成**: `@prompt-optimizer/core` 和 `@prompt-optimizer/ui` 包已成功移除所有单例服务。
+- **已解决**: Web 应用 (`@prompt-optimizer/web`) 和浏览器插件 (`@prompt-optimizer/extension`) 的入口文件 (`App.vue`) 已完成适配，应用**能够正常启动和运行**。
+
+本计划旨在记录并总结 `App.vue` 的适配过程。
+
+## 2. 重构目标
+
+- **修复应用启动失败问题**，使其能正常运行。
+- **完全对齐上层应用与底层服务架构**，采用统一的 `useAppInitializer` 进行服务初始化。
+- **简化 `App.vue`**，使其只负责布局和初始化，将业务逻辑完全委托给 Composables。
+- **采用最新的 Composable 架构**，消费返回 `reactive` 对象而不是多个 `ref` 的 Composable。
+
+## 3. 实施计划
+
+### 阶段一：净化 UI 包 (已完成) ✅
+
+1.  **文件**: `packages/ui/src/index.ts`
+    -   **任务**: 移除所有从 `@prompt-optimizer/core` 重新导出的服务实例。
+    -   **状态**: ✅ **已完成**。UI 包现在只导出组件、Composables、工厂函数和类型。
+
+### 阶段二：创建统一的应用初始化器 (已完成) ✅
+
+1.  **文件**: `packages/ui/src/composables/useAppInitializer.ts` (新建)
+    -   **任务**: 创建一个 Vue Composable，根据环境（Web/Electron）创建并返回所有必要服务的实例。
+    -   **状态**: ✅ **已完成**。
+
+### 阶段三：重构应用入口 (已完成) ✅
+
+此阶段是本次重构的核心，现已**圆满完成**。
+
+1.  **文件**: `packages/web/src/App.vue` 和 `packages/extension/src/App.vue`
+    -   **状态**: ✅ **已完成**。应用已能正常启动。
+    -   **最终实现方案**:
+        1.  **[x] 清理无效导入**:
+            -   在 `<script setup>` 中，删除了所有对单例服务 (`modelManager`, `templateManager` 等) 的直接导入。
+        2.  **[x] 依赖 `useAppInitializer`**:
+            -   在顶层调用 `const { services, isInitializing } = useAppInitializer()` 作为获取所有服务的唯一来源。
+        3.  **[x] 在顶层调用所有业务 Composable**:
+            -   遵循 [Composable 重构计划](./composables-refactor-plan.md) 的成果，所有业务逻辑 Composable (如 `usePromptOptimizer`, `useModelManager`) 都在 `<script setup>` 的顶层被调用。
+            -   这些 Composable 接收 `services` ref 作为参数，并返回一个单一的 `reactive` 对象。
+            -   **示例代码**:
+                ```typescript
+                // App.vue
+                const { services, isInitializing, error } = useAppInitializer();
+                
+                // 在顶层直接调用，传入 services ref
+                const modelManagerState = useModelManager(services);
+                const templateManagerState = useTemplateManager(services);
+                const optimizerState = usePromptOptimizer(services);
+                // ... 其他 Composable
+                ```
+        4.  **[x] 更新模板 (`<template>`)**:
+            -   模板中的所有数据绑定和事件处理，现在都链接到 Composable 返回的 `reactive` 对象的属性上 (e.g., `optimizerState.isIterating`)。
+            -   这解决了之前因传递 `ref` 对象而导致的 prop 类型验证失败问题。
+        5.  **[x] 修复 `computed` 和类型错误**:
+            -   修正了 `App.vue` 中的 `computed` 属性，使其不再错误地访问 `.value`。
+            -   添加了缺失的 i18n 翻译条目，如 `promptOptimizer.originalPromptPlaceholder`。
+            -   通过 `provide` 正确传递了 `templateLanguageService` 等深层依赖。
+        6.  **[x] 推广 `provide`/`inject`**:
+            -   保留了 `provide('services', services)`，并鼓励子组件（如 `ModelSelect.vue`, `DataManager.vue`）通过 `inject` 获取服务，减少了 props 传递。
+
+## 4. 预期成果 (已达成)
+
+- [x] Web 端和插件端应用恢复正常，功能与重构前一致。
+- [x] `App.vue` 代码变得极为简洁，只负责"初始化"和"布局"。
+- [x] 整个应用的启动流程清晰、健壮，完全遵循依赖注入和响应式数据流的最佳实践。
+- [x] 为未来在所有平台（Web/插件/桌面）添加新功能打下坚实的基础。 
+
+## 5. 最新进展：净化 UI 子组件 (已完成) ✅
+
+**背景**: 在 `App.vue` 完成对 `useAppInitializer` 的适配后，发现其下属的多个 UI 组件 (`@prompt-optimizer/ui/components/*`) 仍然直接从 `@prompt-optimizer/core` 导入单例服务，这违反了新的依赖注入架构，并可能导致潜在的 bug 和测试难题。
+
+**任务**: 彻底移除 UI 组件层对服务单例的直接依赖，改为通过 `props` 接收服务实例。
+
+**实施清单**:
+- [x] **`TemplateSelect.vue`**: 移除对 `templateManager` 的直接导入，改为 props 传入。
+- [x] **`ModelSelect.vue`**: 移除对 `modelManager` 的直接导入，改为 props 传入。
+- [x] **`OutputDisplayCore.vue`**: 移除对 `compareService` 的直接导入，改为 props 传入。
+- [x] **`HistoryDrawer.vue`**: 移除对 `historyManager` 的直接导入（该组件已通过 props 接收数据，只需清理无用导入）。
+- [x] **`BuiltinTemplateLanguageSwitch.vue`**: 移除对 `templateManager` 和 `templateLanguageService` 的直接导入，改为 props 传入。
+- [x] **`DataManager.vue`**: 移除对 `dataManager` 的直接导入，改为 props 传入或从 `services` inject。
+- [x] **`TemplateManager.vue`**: 确保从 `services` 注入中获取 `templateManager` 和 `templateLanguageService`，并正确传递给子组件。
+
+**成果**:
+- 所有核心 UI 展示组件均已与服务层解耦。
+- 组件的复用性和可测试性得到显著提升。
+- 整个前端架构更加符合"依赖于接口而非实现"的原则。
+- 项目的架构一致性得到保障，为后续的维护和迭代清除了障碍。
