Synchronous GPU commit step: write the staged buffers into the
mesh's geometry, either via the GPU buffer pool (if enabled) or via
updateInstancedGSplatsMesh. Updates visibleSplatCount on the
mesh's user-data and logs an info line on a zero-splat frame.
Must run synchronously inside the atomic commit stage.
