feat(analysis): Implement Configurable Analysis Template Engine

This commit introduces a comprehensive, template-based analysis orchestration system, refactoring the entire analysis generation workflow from the ground up. Key Changes: 1. **Backend Architecture (`report-generator-service`):** * Replaced the naive analysis workflow with a robust orchestrator based on a Directed Acyclic Graph (DAG) of module dependencies. * Implemented a full topological sort (`petgraph`) to determine the correct execution order and detect circular dependencies. 2. **Data Models (`common-contracts`, `data-persistence-service`):** * Introduced the concept of `AnalysisTemplateSets` to allow for multiple, independent, and configurable analysis workflows. * Created a new `analysis_results` table to persist the output of each module for every analysis run, ensuring traceability. * Implemented a file-free data seeding mechanism to populate default analysis templates on service startup. 3. **API Layer (`api-gateway`):** * Added a new asynchronous endpoint (`POST /analysis-requests/{symbol}`) to trigger analysis workflows via NATS messages. * Updated all configuration endpoints to support the new `AnalysisTemplateSets` model. 4. **Frontend UI (`/config`, `/query`):** * Completely refactored the "Analysis Config" page into a two-level management UI for "Template Sets" and the "Modules" within them, supporting full CRUD operations. * Updated the "Query" page to allow users to select which analysis template to use when generating a report. This new architecture provides a powerful, flexible, and robust foundation for all future development of our intelligent analysis capabilities.

+# 设计文档：可配置的分析模板与编排器
+
+## 1. 概述与目标
+
+### 1.1. 问题陈述
+
+我们当前基于 Rust 的后端缺少执行智能、多步骤财务分析所需的核心业务逻辑。`report-generator-service` 作为此逻辑的载体，其内部实现尚不完整。更重要的是，当前的系统设计缺少一个清晰的、可扩展的方式来管理和复用成套的分析流程，并且在配置初始化方面存在对本地文件的依赖，这不符合我们健壮的系统设计原则。
+
+### 1.2. 目标
+
+本任务旨在我们的 Rust 微服务架构中，设计并实现一个以**分析模板集（Analysis Template Sets）**为核心的、健壮的、可配置的**分析模块编排器**。该系统将允许我们创建、管理和执行多套独立的、包含复杂依赖关系的分析工作流。
+
+为达成此目标，需要完成以下任务：
+1.  **引入分析模板集**：在系统顶层设计中引入“分析模板集”的概念，每个模板集包含一套独立的分析模块及其配置。
+2.  **实现前端模板化管理**：在前端配置中心实现对“分析模板集”的完整 CRUD 管理，并允许在每个模板集内部对分析模块进行 CRUD 管理。
+3.  **构建健壮的后端编排器**：在 `report-generator-service` 中实现一个能够执行指定分析模板集的后端编排器，该编排器需基于拓扑排序来处理模块间的依赖关系。
+4.  **实现无文件依赖的数据初始化**：通过在服务二进制文件中嵌入默认配置的方式，实现系统首次启动时的数据播种（Seeding），彻底移除对本地配置文件的依赖。
+
+## 2. 新数据模型 (`common-contracts`)
+
+为了支持“分析模板集”的概念，我们需要定义新的数据结构。
+
+```rust
+// common-contracts/src/config_models.rs
+
+use serde::{Deserialize, Serialize};
+use std::collections::HashMap;
+
+// 整个系统的分析模板配置，作为顶级对象存储在数据库中
+// Key: 模板ID (e.g., "standard_fundamentals")
+pub type AnalysisTemplateSets = HashMap<String, AnalysisTemplateSet>;
+
+// 单个分析模板集，代表一套完整的分析流程
+#[derive(Serialize, Deserialize, Debug, Clone)]
+pub struct AnalysisTemplateSet {
+    pub name: String, // 人类可读的模板名称, e.g., "标准基本面分析"
+    // 该模板集包含的所有分析模块
+    // Key: 模块ID (e.g., "fundamental_analysis")
+    pub modules: HashMap<String, AnalysisModuleConfig>,
+}
+
+// 单个分析模块的配置 (与之前定义保持一致)
+#[derive(Serialize, Deserialize, Debug, Clone)]
+pub struct AnalysisModuleConfig {
+    pub name: String,
+    pub provider_id: String,
+    pub model_id: String,
+    pub prompt_template: String,
+    // 依赖关系列表，其中的字符串必须是同一个模板集内其他模块的ID
+    pub dependencies: Vec<String>,
+}
+```
+
+## 3. 系统架构与数据流
+
+### 3.1. 高层数据流
+
+1.  **配置流程**:
+    *   **用户** 在 **前端** 与配置页面交互，创建或修改一个“分析模板集”。
+    *   **前端** 向 **API 网关** 发送 `PUT /api/v1/configs/analysis_template_sets` 请求。
+    *   **API 网关** 将请求代理至 **数据持久化服务**，由其将序列化后的 `AnalysisTemplateSets` 对象完整保存到数据库中。
+
+2.  **执行流程**:
+    *   **用户** 在 **前端** 选择一个**分析模板集**，然后为特定的股票代码触发分析。
+    *   **前端** 向 **API 网关** 发送 `POST /api/v1/analysis-requests/{symbol}` 请求，请求体中包含所选的 `template_id`。
+    *   **API 网关** 验证请求，并向 **NATS 消息总线** 发布一条包含 `symbol`, `template_id` 和 `request_id` 的 `GenerateReportCommand` 消息。
+    *   **报告生成服务** 订阅该消息，并根据 `template_id` 启动指定的编排工作流。
+
+## 4. 前端实施计划 (`/config` 页面)
+
+前端配置页面需要重构为两级结构：
+
+1.  **第一级：模板集管理**
+    *   显示一个包含所有“分析模板集”的列表。
+    *   提供“创建新模板集”、“重命名”、“删除模板集”的功能。
+    *   用户选择一个模板集后，进入第二级管理界面。
+
+2.  **第二级：分析模块管理 (在选定的模板集内)**
+    *   **主界面**: 进入模板集后，主界面将以列表形式展示该模板集内所有的分析模块。每个模块将以一个独立的“卡片”形式呈现。
+    *   **创建 (Create)**:
+        *   在模块列表的顶部或底部，将设置一个“新增分析模块”按钮。
+        *   点击后，将展开一个表单，要求用户输入新模块的**模块ID**（唯一的、机器可读的英文标识符）和**模块名称**（人类可读的显示名称）。
+    *   **读取 (Read)**:
+        *   每个模块卡片默认会显示其**模块名称**和**模块ID**。
+        *   卡片可以被展开，以显示其详细配置。
+    *   **更新 (Update)**:
+        *   在展开的模块卡片内，所有配置项均可编辑：
+            *   **LLM Provider**: 一个下拉菜单，选项为系统中所有已配置的LLM供应商。
+            *   **Model**: 一个级联下拉菜单，根据所选的Provider动态加载其可用模型。
+            *   **提示词模板**: 一个多行文本输入框，用于编辑模块的核心Prompt。
+            *   **依赖关系**: 一个复选框列表，该列表**仅显示当前模板集内除本模块外的所有其他模块**，用于勾选依赖项。
+    *   **删除 (Delete)**:
+        *   每个模块卡片的右上角将设置一个“删除”按钮。
+        *   点击后，会弹出一个确认对话框，防止用户误操作。
+
+## 6. 数据库与数据结构设计
+
+为了支撑上述功能，我们需要在 `data-persistence-service` 中明确两个核心的数据存储模型：一个用于存储**配置**，一个用于存储**结果**。
+
+### 6.1. 配置存储：`system_config` 表
+
+我们将利用现有的 `system_config` 表来存储整个分析模板集的配置。
+
+-   **用途**: 作为所有分析模板集的“单一事实来源”。
+-   **存储方式**:
+    -   表中的一条记录。
+    -   `config_key` (主键): `analysis_template_sets`
+    -   `config_value` (类型: `JSONB`): 存储序列化后的 `AnalysisTemplateSets` (即 `HashMap<String, AnalysisTemplateSet>`) 对象。
+-   **对应数据结构 (`common-contracts`)**: 我们在第2节中定义的 `AnalysisTemplateSets` 类型是此记录的直接映射。
+
+### 6.2. 结果存储：`analysis_results` 表 (新)
+
+为了存储每次分析工作流执行后，各个模块生成的具体内容，我们需要一张新表。
+
+-   **表名**: `analysis_results`
+-   **用途**: 持久化存储每一次分析运行的产出，便于历史追溯和未来查询。
+-   **SQL Schema**:
+    ```sql
+    CREATE TABLE analysis_results (
+        id BIGSERIAL PRIMARY KEY,
+        request_id UUID NOT NULL,          -- 关联单次完整分析请求的ID
+        symbol VARCHAR(32) NOT NULL,       -- 关联的股票代码
+        template_id VARCHAR(64) NOT NULL,  -- 使用的分析模板集ID
+        module_id VARCHAR(64) NOT NULL,    -- 产出此结果的模块ID
+        content TEXT NOT NULL,             -- LLM生成的分析内容
+        meta_data JSONB,                   -- 存储额外元数据 (e.g., model_name, tokens, elapsed_ms)
+        created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+        
+        -- 建立索引以优化查询
+        INDEX idx_analysis_results_request_id (request_id),
+        INDEX idx_analysis_results_symbol_template (symbol, template_id)
+    );
+    ```
+-   **对应数据结构 (`common-contracts`)**:
+    ```rust
+    // common-contracts/src/dtos.rs
+
+    #[derive(Serialize, Deserialize, Debug, Clone)]
+    pub struct NewAnalysisResult {
+        pub request_id: Uuid,
+        pub symbol: String,
+        pub template_id: String,
+        pub module_id: String,
+        pub content: String,
+        pub meta_data: serde_json::Value,
+    }
+    ```
+
+## 5. 后端实施计划
+
+### 5.1. `data-persistence-service`
+
+-   **数据初始化 (无文件依赖)**: 实现一次性的、基于硬编码的启动逻辑。
+    1.  在 `data-persistence-service` 的代码中，将 `config/analysis-config.json` 的内容硬编码为一个 Rust 字符串常量。
+    2.  在服务启动时，检查 `system_config` 表中是否存在键为 `analysis_template_sets` 的记录。
+    3.  如果**不存在**，则：
+        a.  解析硬编码的字符串，构建一个默认的 `AnalysisTemplateSet` (例如，ID为 `default`, 名称为 “默认分析模板”)。
+        b.  将这个默认模板集包装进一个 `AnalysisTemplateSets` 的 HashMap 中。
+        c.  将序列化后的 `AnalysisTemplateSets` 对象写入数据库。
+    4.  此机制确保系统在首次部署时，无需任何外部文件即可拥有一套功能完备的默认分析模板。
+-   **新职责**: 实现对 `analysis_results` 表的CRUD操作API。
+
+### 5.2. `api-gateway`
+
+-   **端点更新**: `POST /api/v1/analysis-requests/{symbol}`。
+-   **逻辑变更**:
+    *   该端点现在需要从请求体中解析出 `template_id`。
+    *   它构建的 `GenerateReportCommand` 消息中，必须包含 `template_id` 字段。
+
+### 5.3. `report-generator-service` (核心任务)
+
+`worker.rs` 中的编排逻辑需要进行如下调整和实现：
+
+1.  **消息消费者**: 订阅的 `GenerateReportCommand` 消息现在会包含 `template_id`。
+
+2.  **编排逻辑 (`run_report_generation_workflow`)**:
+    *   **获取配置**: 从 `data-persistence-service` 获取完整的 `AnalysisTemplateSets` 对象。
+    *   **选择模板**: 根据传入的 `template_id`，从 `AnalysisTemplateSets` 中选择出本次需要执行的 `AnalysisTemplateSet`。如果找不到，则记录错误并终止。
+    *   **构建依赖图**: 使用所选模板集中的 `modules` 来构建有向图。强烈推荐使用 `petgraph` crate。
+    *   **拓扑排序**: 对该图执行拓扑排序，**必须包含循环检测**。
+    *   **顺序执行**: 遍历排序后的模块列表，后续的上下文注入、LLM调用和结果持久化逻辑与之前设计一致，但操作范围仅限于当前模板集内的模块。
+
+3.  **补全缺失逻辑**:
+    *   **实现结果持久化**: 调用 `data-persistence-service` 提供的API，将每个模块生成的 `NewAnalysisResult` 存入 `analysis_results` 表。
+
+## 6. 未来工作
+
+### 6.1. 演进至 "Deep Research" 模块
+
+此设计为未来的 "Deep Research" 模块演进奠定了坚实的基础。当该模块准备就绪时，我们可以创建一个新的“分析模板集”，其中的某些模块（如 `news_analysis`）将不再直接调用 LLM，而是调用 Deep Research 服务。Deep Research 服务将执行复杂的数据挖掘，并将高度精炼的结果返回给编排器，再由编排器注入到后续的 LLM 调用中，从而实现“数据驱动”的分析范式。
+
+### 6.2. 引入工具调用框架 (Tool Calling Framework)
+
+为了以一种更通用和可扩展的方式向提示词模板中注入多样化的上下文数据，我们规划引入“工具调用”框架。
+
+-   **概念**: “工具”是指一段独立的、用于获取特定类型数据的程序（例如，获取财务数据、获取实时股价、获取最新新闻等）。
+-   **配置**: 在前端的模块配置界面，除了依赖关系外，我们还将为每个模块提供一个“可用工具”的复选框列表。用户可以为模块勾选需要调用的一个或多个工具。
+-   **执行**:
+    1.  在 `report-generator-service` 的编排器执行一个模块前，它会先检查该模块配置中启用了哪些“工具”。
+    2.  编排器将按顺序执行这些工具。
+    3.  每个工具的输出（例如，格式化为Markdown的财务数据表格）将被注入到一个统一的上下文字段中。
+-   **首个工具**: 我们设想的第一个工具就是 **`财务数据注入工具`**。它将负责获取并格式化财务报表，其实现逻辑与本文档旧版本中描述的“核心逻辑细化”部分一致。
+
+通过此框架，我们可以将数据注入的逻辑与编排器的核心逻辑解耦，使其更易于维护和扩展。**此项为远期规划，不在本轮实施范围之内。**
+

+
+## 1. 背景与目标
+
+### 1.1. 当前问题
+
+当前系统对外部服务（如 Tushare, Finnhub）API Token 的管理方式存在两个主要问题：
+
+1.  **配置方式分裂**:
+    - **敏感凭证 (API Tokens)**: 通过启动时的**环境变量**注入。这种方式虽然安全，但缺乏灵活性，每次修改都需要重新部署或重启服务。
+    - **业务逻辑配置 (AI模型选择等)**: 通过**数据库**统一管理，并支持UI动态调整。
+    - 这种分裂的管理模式增加了系统的运维复杂性，与我们追求的“单一事实源”架构理念不符。
+
+2.  **服务韧性不足**:
+    - 依赖环境变量的服务采取“快速失败” (Fail-Fast) 策略。如果启动时未提供有效的 API Token，服务会立即崩溃退出。
+    - 这种模式虽然能尽早暴露问题，但在一个动态的、持续运行的系统中显得过于“僵硬”。我们期望的行为是：服务在缺少非核心配置时，应能进入一个“降级”状态，待配置就绪后再自动恢复工作，而不是直接停止运行。
+
+### 1.2. 改造目标
+
+本次重构旨在将所有外部服务的 API Token 配置，从环境变量迁移到数据库中，实现与业务逻辑配置的统一管理。具体目标如下：
+
+- **统一配置源**: 将 `system_config` 数据库表作为所有可变配置（包括API Tokens）的唯一事实源。
+- **提升易用性**: 允许用户通过前端UI界面，集中管理和更新所有数据源的 API Token。
+- **增强服务韧性**: 改造数据提供商服务，使其在缺少 API Token 时不会崩溃，而是进入“降级模式”，并能在 Token 被提供后自动恢复正常工作。
+- **简化部署**: 移除对多个环境变量的依赖，使服务的部署和运维过程更加简洁。
+
+---
+
+## 2. 实施方案
+
+本次改造将遵循“后端 -> 服务 -> 前端”的顺序分层实施，确保每一步都有坚实的基础。
+
+### 2.1. 数据模型与持久化层
+
+我们将通过复用 `system_config` 表中现有的 `(config_key, config_value)` 存储模式，来扩展配置管理的能力，使其能够安全地存储和检索数据源的配置。
+
+1.  **定义数据结构**: 在 `common-contracts` 共享库中，定义一个清晰的、用于描述数据源配置的 `DataSourceConfig` 结构体。它将包含 `provider_id`, `api_token`, `api_url` 等字段。
+2.  **复用现有表结构**: 我们将向 `system_config` 表中插入一条新的记录，其 `config_key` 固定为 `"data_sources"`，并将所有数据源的配置集合（一个 `HashMap<String, DataSourceConfig>`）序列化后存入该记录的 `config_value` 字段中。
+3.  **扩展API**: 在 `data-persistence-service` 中增加新的 HTTP API 端点，用于对数据源配置进行增、删、改、查（CRUD）操作。例如：
+    - `GET /api/v1/configs/data-sources`: 获取所有数据源的配置列表。
+    - `PUT /api/v1/configs/data-sources`: 创建或更新所有数据源的配置。
+
+### 2.2. 微服务改造：引入“降级与恢复”模式
+
+这是本次重构的核心。所有依赖外部 API Token 的数据提供商服务 (`finnhub`, `tushare`, `alphavantage`) 都将进行如下改造：
+
+1.  **移除启动时检查**: 删除 `config.rs` 中检查环境变量并导致程序崩溃的逻辑。
+2.  **引入内部状态机**: 每个服务内部将维护一个状态（例如 `State<ServiceOperationalStatus>`)，包含 `Active` 和 `Degraded(reason: String)` 两种状态。
+3.  **动态配置加载**: 服务将不再从环境变量读取 Token，而是在内部启动一个**后台任务**（轮询器），该任务会：
+    - 在服务启动时，以及之后每隔一段时间（例如 60 秒），调用 `data-persistence-service` 的新 API 来获取自己的配置。
+    - 如果成功获取到有效的 Token，则更新服务内部的 API 客户端，并将服务状态设置为 `Active`。此时，服务正常订阅和处理来自 NATS 的消息。
+    - 如果未能获取 Token（或 Token 为空），则将服务状态设置为 `Degraded`，并附上原因（如 "API Token not configured"）。在这种状态下，服务**不会**订阅 NATS 消息队列，避免接收无法处理的任务。
+4.  **更新健康检查**: 服务的 `/health` 端点将反映其内部状态。当处于 `Degraded` 状态时，健康检查接口应返回相应的状态码和信息，以便监控系统能够清晰地了解服务当前是否可用。
+
+### 2.3. 前端UI实现
+
+为了让用户能够方便地管理这些配置，我们将在前端进行如下调整：
+
+1.  **创建新UI组件**: 在 `/config` 页面，新增一个名为“数据源配置”的管理面板。
+2.  **功能实现**: 该面板将提供一个表单或列表，允许用户：
+    - 查看当前所有数据源（Tushare, Finnhub 等）的配置状态。
+    - 为每个数据源输入或更新其 API Token。
+    - 保存更改。点击保存后，前端将调用 `data-persistence-service` 的新 API，将更新后的配置持久化到数据库中。

+
+## 3. 详细任务清单
+
+### 第一阶段：后端基础
+
+- [x] ~~**任务 BE-1**: 在 `common-contracts` 中定义 `DataSourceConfig` 和 `DataSourceProvider` 等共享数据结构。~~
+- [x] ~~**任务 BE-3**: 在 `data-persistence-service` 中实现对数据源配置的 CRUD 业务逻辑。~~
+- [x] ~~**任务 BE-4**: 在 `data-persistence-service` 中暴露 `GET /api/v1/configs/data-sources` 和 `PUT /api/v1/configs/data-sources` 这两个 API 端点。~~
+
+### 第二阶段：微服务改造
+
+- [x] ~~**任务 SVC-1**: **(Finnhub)** 重构 `finnhub-provider-service`：~~
+    - [x] ~~移除 `config.rs` 中的 `FINNHUB_API_KEY` 环境变量加载逻辑。~~
+    - [x] ~~实现内部状态机 (`Active`/`Degraded`) 和动态配置轮询器。~~
+    - [x] ~~修改 `/health` 端点以反映内部状态。~~
+    - [x] ~~调整 NATS 消息订阅逻辑，只在 `Active` 状态下进行订阅。~~
+- [x] ~~**任务 SVC-2**: **(Tushare)** 以 `finnhub-provider-service` 为模板，对 `tushare-provider-service` 进行相同的重构。~~
+- [x] ~~**任务 SVC-3**: **(Alphavantage)** 以 `finnhub-provider-service` 为模板，对 `alphavantage-provider-service` 进行相同的重构。~~
+- [x] ~~**任务 SVC-4**: **(审查)** 审查 `report-generator-service` 的 LLM 配置加载逻辑，确保其与新的动态配置模式在设计理念上保持一致。~~
+
+### 第三阶段：前端实现
+
+- [x] **任务 FE-1**: 在 `/config` 页面设计并实现“数据源配置”UI 组件。
+- [x] **任务 FE-2**: 实现 `useApi.ts` 中用于获取和更新数据源配置的 hooks。
+- [x] **任务 FE-3**: 将 UI 组件与 API hooks 连接，完成前端的完整功能。
+- [x] **任务 FE-4**: 调整 `/llm-config` 页面，使其在UI/UX风格上与新的“数据源配置”面板保持一致性。
