📂 File-Level Changes Summary
• MainWindow.xaml: Named TabControl and added SelectionChanged handler for tab tracking.
• MainWindow.xaml.cs: Added UpdateCustomSetState() to sync custom recoil mode with RecoilEngine based on tab focus and toggle state.
• RecoilEngine.cs: Added CustomModeActive, CustomRecoilX, CustomRecoilY fields; HandleRecoilTick() checks custom mode first before falling back to mergedSets lookup.
