Refactor: add command allocator & render target strategies

Major refactor of graphics infrastructure:
- Introduce ICommandAllocator and D3D12CommandAllocator for explicit command buffer management.
- Change ICommandBuffer.Begin to require an allocator.
- Add IRenderTargetStrategy abstraction with swap chain and texture implementations.
- Update IRenderer to use RenderTargetStrategy instead of direct handle.
- Add DPI scaling support to swap chains (ScaleX/ScaleY, SetScale).
- RenderSystem now supports thread-safe swap chain resize requests.
- Remove persistent copy command buffer; use per-frame allocators.
- Make Logger public/static and clean up API visibility.
- Update .editorconfig and debug layer enablement.
These changes improve modularity, DPI-awareness, and future extensibility.
