Implement core entity management features

Browse Source 
Added `Archetype` struct with chunk management and disposal.
Added `BitSet` class for managing collections of bits.
Added `Class1.cs` as a placeholder for graphics functionality.
Added `ComponentData` struct and `ComponentPool` class for component management.
Added `ComponentRegistry` for efficient component registration.
Added `EntityChangeQueue` as a placeholder for future changes.
Added `Helpers.ttinclude` and `QueryRefComponent.tt` for code generation.
Added `Signature` struct for managing component signatures.
Added `World` struct to manage the game world and entities.
Added `QueryRefComponent` delegates for querying entities.

Changed `Archetype.cs` to implement `IDisposable`.
Changed `AssemblyInfo.cs` to update global using directives.
Changed `Chunk.cs` to introduce `ChunkCollection` for chunk management.
Changed `Component.cs` to refine component management methods.
Changed `Entity.cs` to improve properties and methods.
Changed `Ghost.Entities.csproj` to update project properties.
Changed `Program.cs` to demonstrate entity creation and querying.
Changed `World.Query.cs` to facilitate querying with components.
