• Typo in namespace 'ReractiveUI'; rename to 'ReactiveUI' to match project and folder naming.

• Typo in namespace 'ReractiveUI'; rename to 'ReactiveUI' to match project and folder naming.

• RootNamespace has typo 'ReractiveUI'; update to 'ReactiveUI' to align with package and code structure.

<RootNamespace>Avalonia.Xaml.Interactions.ReractiveUI</RootNamespace>

• Add unit tests for NavigateToViewModelAction covering enabled/disabled states and null ViewModel or parameter scenarios to ensure correct behavior.

public override object Execute(object? sender, object? parameter)

src/Avalonia.Xaml.Interactions.ReactiveUI/NavigateBackAction.cs:33

• Add unit tests for NavigateBackAction to cover cases when the navigation stack is empty and when it contains entries.

public override object Execute(object? sender, object? parameter)

src/Avalonia.Xaml.Interactions.ReactiveUI/NavigateToViewModelAction.cs:1

• The using directive 'using Avalonia.Reactive' doesn't match an existing namespace; likely intended 'using System.Reactive' or can be removed if unused.

using Avalonia.Reactive;

• [nitpick] For consistency with other action classes, consider renaming this to 'NavigateAndResetAction'.

public class NavigateAndReset : StyledElementAction

• This action has no unit tests; consider adding tests for the Execute method in both enabled/disabled and empty-stack scenarios.
