Tasks

• Task: WPF MVVM & XAML DataTemplate Migration #102 WPF MVVM & XAML DataTemplate Migration: Move dynamic UI construction out of MainWindow.xaml.cs (4,300+ lines) into declarative XAML layouts using ViewModels, bindings, and DataTemplate patterns.
• Task: Event-Driven Process Hooks #103 Event-Driven Process Hooks: Replace background active process polling (Process.GetProcesses() every 1.5s) in HookEngine with event-driven system notifications (such as SetWinEventHook) to eliminate background CPU and GC garbage collector allocations.
• Task: State Channel (IPC / Watcher) Migration #104 State Channel (IPC / Watcher) Migration: Replace the UI thread's blocking 3-second disk polling loop with a Named Pipe IPC or a dynamic FileSystemWatcher pattern.
