9. Intent Result, Dialog, dan View

// Tidak ada output — intent selesai diam-diam
func perform() async throws -> some IntentResult {
    try await SomeService.doWork()
    return .result()
}

// Dengan dialog — Siri ucapkan ini setelah selesai
func perform() async throws -> some IntentResult & ProvidesDialog {
    return .result(dialog: "Selesai! Kopi kamu sedang disiapkan.")
}

// Dengan value — bisa di-chain ke intent berikutnya di Shortcuts
func perform() async throws -> some IntentResult & ReturnsValue<TaskEntity> {
    let task = try await TaskRepository.shared.create(title: title, priority: priority, dueDate: dueDate)
    return .result(value: TaskEntity(task: task))
}

// Dengan dialog dan value sekaligus
func perform() async throws -> some IntentResult & ReturnsValue<Int> & ProvidesDialog {
    let count = try await TaskRepository.shared.fetchPending().count
    return .result(
        value: count,
        dialog: "Kamu punya \(count) tugas yang belum selesai."
    )
}

struct ShowSummaryIntent: AppIntent {
    static var title: LocalizedStringResource = "Tampilkan Ringkasan"
    
    func perform() async throws -> some IntentResult & ShowsSnippetView {
        let stats = try await TaskRepository.shared.fetchStats()
        
        return .result {
            // SwiftUI view yang muncul di Siri / Shortcuts result
            TaskSummaryView(
                total: stats.total,
                completed: stats.completed,
                pending: stats.pending
            )
        }
    }

    let total: Int
    let completed: Int
    let pending: Int
    
    var body: some View {
        VStack(spacing: 12) {
            HStack {
                StatCard(title: "Total", value: total, color: .blue)
                StatCard(title: "Selesai", value: completed, color: .green)
                StatCard(title: "Pending", value: pending, color: .orange)
