Class BufferRecord

src/host/ui/buffer_model.h:46–57

One buffer as the UI chrome sees it: enough metadata to render a buffer-list row and build a Stage, plus the raw pixel bytes ready for GlCanvas upload. IpcBufferModel populates these from IPC-decoded buffers; MockBufferModel below fabricates them deterministically.
