Extensions and WebGPU

WebGL 2 is finished: new capabilities now arrive only as extensions, and the effort that once went into a WebGL with compute shaders went into WebGPU instead. This section maps what the extensions offer in 2026 on this book's two renderers, then places WebGL beside WebGPU as the bridge into WebGPU.
