feat(P2-M4): dual-system API integration + knowledge base management

Backend:
- experience router: PUT update API + import from plan/result API
- auto conclusion generator from metrics
- import from plan: batch import all OK results with auto-generated conclusion
- import from result: single result import

System 2 (api_client):
- 10 experience library methods (list/get/create/update/delete/import)
- 6 analytics methods (metrics/stats/similar/trend/pareto/sensitivity/overview)
- sync_local_experience_to_web: dedup sync from local DB to web
- expanded from 17 to 27 methods

Frontend:
- ExperienceList: import from plan dialog + edit dialog + delete confirmation
- experienceApi: add update/importFromPlan/importFromResult

Tests:
- test_integration.py: 55 test points, full closed-loop verification
  health -> project -> plan -> download -> upload results -> import experience
  -> CRUD -> analytics (stats/similar/trend/pareto/sensitivity/overview)
- all 55 tests passing

+## 2026-08-27 18:30 — P2-M4 完成：双系统API联调 + 知识库管理
+
+### 成果
+
+#### 后端：经验库CRUD增强
+- `web/backend/app/routers/experience.py`（重写，~280行）：
+  - **PUT /api/experience/{id}**：更新经验案例（conclusion/tags/rating/params/metrics/topology）
+  - **POST /api/experience/from-plan/{plan_id}**：从方案的所有OK结果批量导入经验库
+    - 自动生成conclusion（基于指标值的描述：转矩/效率/脉动/损耗+性能评估）
+    - 支持自定义tags/rating/auto_conclusion参数
+    - 从plan_json中获取topology/model_path（兼容SimulationPlan模型无此字段）
+  - **POST /api/experience/from-result/{result_id}**：从单个结果导入经验库
+  - **_generate_conclusion()**：自动结论生成器（ASCII-only文本）
+
+#### 系统二：API客户端增强
+- `src/api_client.py`（+180行，从17方法扩展到27方法）：
+  - **经验库方法**（10个）：list/get/create/update/delete/importFromPlan/importFromResult
+  - **分析方法**（6个）：getMetricDefs/getExperienceStats/findSimilarExperience/getPlanTrend/getPlanPareto/getPlanSensitivity/getProjectOverview
+  - **sync_local_experience_to_web()**：本地经验库同步到Web端（去重，按plan_id+params签名）
+  - 系统二可完整调用Web端所有API，实现双向通信
+
+#### 前端：经验库管理页面增强
+- `web/frontend/src/views/ExperienceList.vue`（+200行）：
+  - **Import from Plan按钮**：选择方案+tags+rating+auto_conclusion开关，一键批量导入
+  - **编辑功能**：表格操作列Edit按钮，弹窗编辑conclusion/tags(多选可创建)/rating/topology
+  - **删除功能**：操作列Delete按钮，确认弹窗后删除
+  - 导入弹窗支持方案下拉选择（从API加载所有方案）
+- `web/frontend/src/api/index.ts`：experienceApi新增update/importFromPlan/importFromResult
+
+#### 双系统联调集成测试
+- `web/backend/test_integration.py`（~300行，55个测试点）：
+  - 完整闭环测试：健康检查→创建项目→创建方案→下载方案→上传结果CSV→查询结果→导入经验库→经验库CRUD→分析API（统计/相似/趋势/Pareto/敏感性/项目概览/指标定义）→清理
+  - 使用FastAPI TestClient，无需真实服务器
+  - 模拟系统二上传scan_results.csv（5行，4OK+1FAILED）
+  - 验证数据一致性和API响应格式
+
+### Git提交
+- 待提交（本轮完成后统一提交）
+
+### 验证结果
+1. **集成测试**：55/55全部通过（16个测试组）
+2. **后端导入验证**：`from app.main import app` 成功，所有路由注册
+3. **前端构建**：vite build成功（22.62s），ExperienceList.js 16.48kB
+4. **系统二API客户端**：27个方法，10经验库+6分析+11原有
+5. **ASCII检查**：所有新增/修改.py文件纯ASCII
+
+### 双系统联调架构
+```
+系统一（Web端）                    系统二（本地EXE）
+┌─────────────┐                    ┌─────────────┐
+│  FastAPI    │◄─── REST API ────► │ api_client  │
+│  + SQLite   │   下载方案/上传结果  │  + MotorCAD │
+│  + Vue3     │   经验库同步/分析    │  + 本地GUI  │
+└─────────────┘                    └─────────────┘
+       │                                    │
+       └────────── 经验库双向同步 ──────────┘
+```
+
+### 关键设计决策
+1. **经验库导入从结果而非方案**：只导入status=OK的结果，避免失败数据污染经验库
+2. **自动结论生成**：基于指标值的简单规则生成，用户可后续编辑完善
+3. **系统二api_client纯urllib**：无第三方依赖，可在任何Python环境运行
+4. **本地→Web同步去重**：按plan_id+params签名去重，避免重复导入
+5. **SimulationPlan兼容**：topology/model_path从plan_json获取，不依赖模型字段
+
+### 待优化（后续里程碑）
+- 经验库导入可增加人工审核步骤（先存为draft，确认后入库）
+- 系统二本地经验库可增加定时自动同步到Web端
+- 经验库可增加版本管理和变更历史
+- P2-M5验收时可增加端到端真实Motor-CAD仿真联调测试
+
