feat: push constants + UBO descriptor sets — rotating triangle with VP matrix

- Push constants: rotation angle (float) sent to vertex shader via vkCmdPushConstants - UBO + descriptor sets: VP matrix (mat4) in uniform buffer, bound via VkDescriptorSet - New Vulkan functions: vkCreateDescriptorSetLayout, vkCreateDescriptorPool, vkAllocateDescriptorSets, vkUpdateDescriptorSets, vkCmdBindDescriptorSets, vkCmdPushConstants - New structs: VkPushConstantRange, VkDescriptorSetLayoutBinding, VkDescriptorSetLayoutCreateInfo, VkDescriptorPoolCreateInfo, VkDescriptorPoolSize, VkDescriptorSetAllocateInfo, VkWriteDescriptorSet, VkDescriptorBufferInfo - Per-frame UBO buffers (HOST_VISIBLE|HOST_COHERENT, 64 bytes each) - Perspective projection + look-at camera (static, no ECS yet) - Cleaned up debug logging in VulkanContext - Zero validation errors
