Refactor project structure and improve performance

Changed the `ProjectRepository` class to be static for easier usage.
Changed `ProjectService` constants to public properties for accessibility.
Changed `App.xaml` to consolidate theme resources into `Override.xaml`.
Changed `App.xaml.cs` to implement an `AppStateMachine` for better state management.
Changed `ConsolePage` and `HierarchyPage` to utilize the new ViewModel structure.
Changed `ProjectPage` to use the `ExplorerItem` model for asset display.
Changed `Entity` and `EntityManager` to enhance component management with a new `IComponentData` interface.
Changed the `Logger` class to introduce structured logging functionality.
Changed the system architecture to support dependency management for better organization.
Changed the `QueryEnumerable` class to allow for more flexible entity queries.
Changed the `TypeHandle` class to improve efficiency in retrieving type handles.
Changed the `World` class to support robust world management and multiple worlds.
Updated the `Test` class to demonstrate the new entity and component management system.
