refactor: 通用技能按类别拆分为独立目录

skills/ → skills-dev(9), skills-req(10), skills-ops(4),
skills-integration(8), skills-biz(4), skills-workflow(7)

generate-marketplace.py 改为自动扫描所有 skills-* 目录。

+# iOS 测试 (XCTest + Swift Concurrency)
+
+## 测试框架
+
+- **XCTest**: Apple 官方测试框架
+- **Swift Testing**: Swift 6 新测试框架 (可选)
+- **ViewInspector**: SwiftUI 视图测试 (第三方)
+
+## 运行测试
+
+```bash
+# 全部测试
+xcodebuild test \
+    -scheme AI-Proj-iOS \
+    -destination 'platform=iOS Simulator,name=iPhone 16' \
+    -quiet
+
+# 特定测试类
+xcodebuild test \
+    -scheme AI-Proj-iOS \
+    -destination 'platform=iOS Simulator,name=iPhone 16' \
+    -only-testing:AI-Proj-iOSTests/DashboardViewModelTests
+
+# 覆盖率
+xcodebuild test \
+    -scheme AI-Proj-iOS \
+    -destination 'platform=iOS Simulator,name=iPhone 16' \
+    -enableCodeCoverage YES
+```

+
+## 关键模式
+
+### 1. Mock 服务 — Result 注入
+
+```swift
+class MockTaskService: TaskServiceProtocol {
+    var fetchTasksResult: Result<TaskListResponse, Error> = .success(.mock)
+
+    func fetchTasks(...) async throws -> TaskListResponse {
+        switch fetchTasksResult {
+        case .success(let response): return response
+        case .failure(let error): throw error
+        }
+    }
+}
+```
+
+所有 Mock 服务统一用 `Result` 属性控制成功/失败返回。
+
+### 2. ViewModel 测试 — @MainActor + async
+
+```swift
+@MainActor
+final class DashboardViewModelTests: XCTestCase {
+    var sut: DashboardViewModel!
+    var mockService: MockDashboardAggregationService!
+
+    override func setUp() {
+        super.setUp()
+        mockService = MockDashboardAggregationService()
+        sut = DashboardViewModel(dashboardService: mockService)
+    }
+
+    override func tearDown() {
+        sut = nil; mockService = nil
+        super.tearDown()
+    }
+
+    func testLoadDashboardData_Success() async {
+        mockService.fetchDashboardDataResult = .success(expectedData)
+        await sut.loadDashboardData()
+        XCTAssertFalse(sut.isLoading)
+        XCTAssertEqual(sut.todayStats.completedTasks, 5)
+    }
+}
+```
+
+要点：`@MainActor` + `async` 测试方法 + setUp/tearDown 重置。
+
+### 3. Mock 数据工厂 — 静态 `.mock()` 方法
+
+```swift
+extension TaskModel {
+    static func mock(id: Int = 1, status: TaskStatus = .todo) -> TaskModel {
+        TaskModel(id: id, title: "Mock Task", status: status, ...)
+    }
+}
+
+extension TaskListResponse {
+    static var mock: TaskListResponse {
+        TaskListResponse(tasks: [.mock(id: 1), .mock(id: 2)], total: 2, page: 1, pageSize: 20)
+    }
+}
+```
+
+### 4. 模型解码测试 — JSON → Model
+
+```swift
+func testTaskModel_DecodesFromJSON() throws {
+    let json = """
+    { "id": 123, "status": "in_progress", "priority": "high", ... }
+    """.data(using: .utf8)!
+
+    let task = try decoder.decode(TaskModel.self, from: json)
+    XCTAssertEqual(task.status, .inProgress)
+}
+```
+
+### 5. SwiftUI 视图测试 — ViewInspector
+
+```swift
+extension EnhancedStatsSection: Inspectable {}
+
+func testStatsSection_DisplaysCorrectValues() throws {
+    let view = EnhancedStatsSection(stats: .mock)
+    let text = try view.inspect().find(text: "5")
+    XCTAssertNotNil(text)
+}
+```
+
+## 最佳实践
+
+1. **@MainActor** — ViewModel 测试必须在主线程
+2. **Mock 所有依赖** — 协议抽象 + Result 注入
+3. **async/await** — 避免 XCTestExpectation 回调
+4. **数据工厂** — `.mock()` 静态方法，参数带默认值
+5. **隔离测试** — setUp/tearDown 重置所有状态
+6. **命名** — `test<Method>_<Scenario>` 格式

+|--------|------|
+| `Cmd + U` | 运行所有测试 |
+| `Ctrl + Opt + Cmd + U` | 运行当前测试方法 |
+| `Ctrl + Opt + Cmd + G` | 重新运行上次测试 |
+| `Cmd + 6` | Test Navigator |
