@hatch:gpu v0.2.11

GPU primitives + 2D/3D renderers. Device, Buffer, Texture, Sampler, ShaderModule, BindGroup, RenderPipeline, CommandEncoder, RenderPass on the bottom; Camera2D/3D, Renderer2D (sprite batcher), Renderer3D (lit), Mesh, Material on top. wgpu on native, WebGPU on web — same Wren API both targets.
