Native SDK gpu-dashboard example

This example combines native app chrome, a gpu_surface, and a retained canvas display list:

Native toolbar, sidebar, and statusbar controls.
A GPU surface registered with explicit presentation settings and a dashboard display list.
Retained widget semantics for dashboard lists, forms, data grids, popovers, and scrolling.
A glass popover rendered with retained widget backdrop blur.
A WebView inspector sibling in the same split layout.
Frame diagnostics for canvas profile risk, work units, commands, batches, and dirty regions.

Run with the macOS system backend. The GPU dashboard defaults to ReleaseFast; pass -Doptimize=Debug only when debugging renderer internals.

native dev

Run the headless canvas and scene tests:

native test -Dplatform=null
