feat(rendering): compute pass infrastructure, IPipeline, GraphicPass/ComputePass split

[JeanPhilippeKernel]

Summary

• IPipeline virtual base — shared fields (Shader, Device, Handle, Layout) and interface (GetBindPoint, Bake, Dispose). GraphicPipeline and ComputePipeline both derive from it.

• RenderPass split — RenderPass is now a pure virtual base. GraphicPass owns all attachment, pipeline, render-area, and descriptor-binding state. ComputePass owns only ComputePipeline* Pipeline. The render graph continues to store RenderPass* uniformly.

• IComputeCallbackPass fully implemented — Compile() creates a ComputePass via UseComputeShader(); Execute() calls BindPipeline(cp->Pipeline) then delegates to ExecuteCompute().

• CommandBuffer::BindPipeline(IPipeline)* — replaces the graphic-only overload. Dispatches via pipeline->GetBindPoint() so it works for both pipeline types. m_active_pipeline + m_in_render_pass replace m_active_render_pass; BindDescriptorSets, BindDescriptorSet, PushConstants use m_active_pipeline directly.

• BeginRenderPass/BeginSecondary typed as GraphicPass* — compile error to pass a compute pass.

• VulkanDevice::CreateRenderPass — dispatches to GraphicPass or ComputePass based on spec.Type.

• ContainerCommon.h — extracts EntryState and hash_compute from HashMap.h and UnorderedHashMap.h, fixing a latent ODR redefinition triggered when both headers appear in the same translation unit.

• GraphicPass::BoundBindings — std::setstd::string replaced with Core::Containers::HashSet. Arena-allocated, no STL heap allocation.

Test plan

• Build passes clean with pre-push clang-format hook
• Engine runs at 120 fps, no validation errors
• Mesh upload, buffer binding, and descriptor sets confirmed working via Console output
