feat: 搭建 Vulkan 1.4 渲染器骨架，绘制旋转 3D 立方体

使用 Vulkan 1.4 现代路径初始化引擎骨架： - 用 Shader Object (VK_EXT_shader_object) 替代传统 VkPipeline - 用 Dynamic Rendering 替代 RenderPass/Framebuffer - 用 Synchronization2 管理 barrier 核心模块： - Window：GLFW 封装，GLFW_NO_API 模式，兼容 Wayland - Log：spdlog 封装 - Types：u32/u64/f32 类型别名 Vulkan 后端： - Device：Instance、PhysicalDevice、LogicalDevice、Queue 及 feature 查询 - Swapchain：Image、ImageView、DepthBuffer、Recreate - ShaderManager：SPIR-V 加载与 ShaderEXT 创建 - CommandManager：CommandPool 与主 CommandBuffer - SyncManager：per-frame Fence 与 ImageAvailable semaphore，per-image RenderFinished semaphore，2 frames in flight - MemoryAllocator：内存子分配器，256MB block，persistent mapping - Buffer：VertexBuffer、IndexBuffer、UniformBuffer 封装 - UniformBuffer：每帧上传 MVP 矩阵 - DescriptorManager：DescriptorSetLayout、DescriptorPool、DescriptorSet 及更新 Renderer： - 协调所有子系统 - 绘制每面不同颜色的旋转 3D 立方体 - 启用 depth test，MVP 矩阵由 GLM 计算构建： - CMake 组织 Engine 静态库与 App 可执行文件 - glfw、glm、spdlog 通过 add_subdirectory 引入
