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

Browse Source

- 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
