feat(ios): Fix iOS build and integrate SwiftTerm for terminal emulation

Major improvements to the iOS VibeTunnel app:

SwiftTerm Integration:
- Properly integrated SwiftTerm 1.2.5 for terminal emulation
- Fixed naming conflicts and API compatibility issues
- Added proper actor isolation with @preconcurrency
- Terminal data now feeds correctly via SSE streams

Session Management:
- Fixed session model to match Go server's JSON response format
- Added CodingKeys mapping for field name differences (cmdline, cwd, etc.)
- Support for "starting" session status
- Enhanced date parsing for both ISO8601 and RFC3339 formats

Working Directory Fixes:
- Changed default working directory from iOS sandbox to server paths
- Now uses ~/ as default (matching web frontend)
- Added common server directories as quick options
- Server expands ~ to actual home directory

Terminal Streaming:
- Implemented Asciinema cast v2 format parsing
- SSE client properly handles output, resize, and exit events
- Added terminal snapshot loading for existing sessions
- Fixed special key handling with proper ANSI escape sequences

UI Improvements:
- Updated session list to grid layout (2 columns)
- Added session count and "Kill All" functionality
- Redesigned session cards with inline kill/clean buttons
- Shows command and working directory in session preview

Error Handling:
- Added comprehensive logging for debugging
- Enhanced error messages for better user experience
- Detailed API request/response logging
- Network error descriptions (connection refused, timeout, etc.)

Server Configuration:
- Set default server address to 127.0.0.1:4020
- Sessions now created with spawn_terminal: false for PTY mode
- Both web and iOS clients can share terminal sessions

The iOS app now provides a full terminal experience using SwiftTerm,
mirroring the web frontend's functionality with proper server integration.

+# Modern Swift Development
+
+Write idiomatic SwiftUI code following Apple's latest architectural recommendations and best practices.
+
+## Core Philosophy
+
+- SwiftUI is the default UI paradigm for Apple platforms - embrace its declarative nature
+- Avoid legacy UIKit patterns and unnecessary abstractions
+- Focus on simplicity, clarity, and native data flow
+- Let SwiftUI handle the complexity - don't fight the framework
+
+## Architecture Guidelines
+
+### 1. Embrace Native State Management
+
+Use SwiftUI's built-in property wrappers appropriately:
+- `@State` - Local, ephemeral view state
+- `@Binding` - Two-way data flow between views
+- `@Observable` - Shared state (iOS 17+)
+- `@ObservableObject` - Legacy shared state (pre-iOS 17)
+- `@Environment` - Dependency injection for app-wide concerns
+
+### 2. State Ownership Principles
+
+- Views own their local state unless sharing is required
+- State flows down, actions flow up
+- Keep state as close to where it's used as possible
+- Extract shared state only when multiple views need it
+
+### 3. Modern Async Patterns
+
+- Use `async/await` as the default for asynchronous operations
+- Leverage `.task` modifier for lifecycle-aware async work
+- Avoid Combine unless absolutely necessary
+- Handle errors gracefully with try/catch
+
+### 4. View Composition
+
+- Build UI with small, focused views
+- Extract reusable components naturally
+- Use view modifiers to encapsulate common styling
+- Prefer composition over inheritance
+
+### 5. Code Organization
+
+- Organize by feature, not by type (avoid Views/, Models/, ViewModels/ folders)
+- Keep related code together in the same file when appropriate
+- Use extensions to organize large files
+- Follow Swift naming conventions consistently
+
+## Implementation Patterns
+
+### Simple State Example
+```swift
+struct CounterView: View {
+    @State private var count = 0
+    
+    var body: some View {
+        VStack {
+            Text("Count: \(count)")
+            Button("Increment") { 
+                count += 1 
+            }
+        }
+    }
+}
+```
+
+### Shared State with @Observable
+```swift
+@Observable
+class UserSession {
+    var isAuthenticated = false
+    var currentUser: User?
+    
+    func signIn(user: User) {
+        currentUser = user
+        isAuthenticated = true
+    }
+}
+
+struct MyApp: App {
+    @State private var session = UserSession()
+    
+    var body: some Scene {
+        WindowGroup {
+            ContentView()
+                .environment(session)
+        }
+    }
+}
+```
+
+### Async Data Loading
+```swift
+struct ProfileView: View {
+    @State private var profile: Profile?
+    @State private var isLoading = false
+    @State private var error: Error?
+    
+    var body: some View {
+        Group {
+            if isLoading {
+                ProgressView()
+            } else if let profile {
+                ProfileContent(profile: profile)
+            } else if let error {
+                ErrorView(error: error)
+            }
+        }
+        .task {
+            await loadProfile()
+        }
+    }
+    
+    private func loadProfile() async {
+        isLoading = true
+        defer { isLoading = false }
+        
+        do {
+            profile = try await ProfileService.fetch()
+        } catch {
+            self.error = error
+        }
+    }
+}
+```
+
+## Best Practices
+
+### DO:
+- Write self-contained views when possible
+- Use property wrappers as intended by Apple
+- Test logic in isolation, preview UI visually
+- Handle loading and error states explicitly
+- Keep views focused on presentation
+- Use Swift's type system for safety
+
+### DON'T:
+- Create ViewModels for every view
+- Move state out of views unnecessarily
+- Add abstraction layers without clear benefit
+- Use Combine for simple async operations
+- Fight SwiftUI's update mechanism
+- Overcomplicate simple features
+
+## Testing Strategy
+
+- Unit test business logic and data transformations
+- Use SwiftUI Previews for visual testing
+- Test @Observable classes independently
+- Keep tests simple and focused
+- Don't sacrifice code clarity for testability
+
+## Modern Swift Features
+
+- Use Swift Concurrency (async/await, actors)
+- Leverage Swift 6 data race safety when available
+- Utilize property wrappers effectively
+- Embrace value types where appropriate
+- Use protocols for abstraction, not just for testing
+
+## Summary
+
+Write SwiftUI code that looks and feels like SwiftUI. The framework has matured significantly - trust its patterns and tools. Focus on solving user problems rather than implementing architectural patterns from other platforms.
