W3 of the oak task list. SurfaceBridge wraps an engine wgpu (Metal) texture into an IOSurface-backed CVPixelBuffer for gpui's Surface element: a reused pixel buffer created with kCVPixelBufferIOSurfacePropertiesKey + MetalCompatibility, aliased to a Metal texture via gpui_media's CVMetalTextureCache, with a GPU-to-GPU MTLBlitCommandEncoder copy (a device.poll(Wait) before the blit keeps the v1 path correct and synchronous). A CPU readback fallback (stage_readback/finish_readback) works on any backend. The surface_bridge demo (demo feature) streams a moving test pattern through the bridge into a window and prints FPS; smoke-verified on macOS at 1280x720. Windows/Linux paths are left for a follow-up (noted in docs/zh). 2 tests pass.
