update XAML namespace references and converters.

[zdpcdt]

This pull request primarily refactors how value converters are referenced and registered in XAML files, moving from CLR/using namespaces to URI-based XML namespaces and consolidating converter registration. It also removes unused or redundant converter implementations in favor of shared or updated ones, and updates the package reference for Irihi.Avalonia.Shared. These changes improve maintainability, consistency, and integration with shared resources.

Converter Refactoring and Namespace Updates:

• All XAML files now use the https://irihi.tech/semi XML namespace (aliased as semi) for referencing converters, replacing previous clr-namespace or using references. This includes updating all converter usages in Carousel.axaml, ProgressBar.axaml, and SemiPopupAnimations.axaml. [1] [2] [3] [4] [5] [6] [7] [8]

• The assembly info now adds a new XML namespace definition for Semi.Avalonia.Converters under https://irihi.tech/semi, making all converters in that namespace accessible via the URI.

Converter Implementation Updates:

• The custom KeyToPathConverter and TreeViewItemIndentConverter implementations have been removed from the codebase, and their usages in XAML replaced with shared or alternative converters (e.g., ResourceConverter). [1] [2] [3] [4]

• PlacementToRenderTransformOriginConverter and PositionToAngleConverter have been refactored to inherit from MarkupValueConverter (from Irihi.Avalonia.Shared.Converters) and simplified using C# switch expressions. [1] [2]

Dependency and Project File Updates:

• The project now references Irihi.Avalonia.Shared version 0.3.1 (up from 0.3.0), and removes the now-unused KeyToPathConverter.cs from compilation.

Avalonia XAML Resource Updates:

• XAML resources in ManagedFileChooser.axaml now use the iri namespace and ResourceConverter for icon resources, aligning with the new converter and namespace conventions. [1] [2]

These changes collectively modernize and standardize how converters are used and referenced throughout the project, leveraging shared resources and simplifying maintenance.

Pull Request Overview

This pull request modernizes XAML namespace usage by replacing CLR/using namespace references with URI-based XML namespaces for value converters, and consolidates converter registration under the https://irihi.tech/semi namespace. The changes also remove redundant converter implementations and update the shared library dependency.

• Replace CLR namespace references with URI-based XML namespace (https://irihi.tech/semi) for all converter usages
• Remove unused converter implementations (KeyToPathConverter, TreeViewItemIndentConverter) and refactor existing converters to inherit from MarkupValueConverter
• Update Irihi.Avalonia.Shared package reference from version 0.3.0 to 0.3.1

src/Semi.Avalonia/Converters/PlacementToRenderTransformOriginConverter.cs:1

• The ConvertBack method was removed from PlacementToRenderTransformOriginConverter but the method signature is still present. This converter works with PlacementMode enum values, not numeric values, so ConvertBack should either throw NotImplementedException or be removed entirely.
