FrameStats gains the geometry pool's used/capacity bytes and, on desktop,
the device-wide used/total reported by the driver (NVML via dlopen, or
amdgpu/i915 sysfs, matched to the wgpu adapter's vendor/device id so a
switchable-graphics laptop reports the card wgpu actually picked). The
device query is polled once a second, not per frame. Web has no VRAM
query, so the device figure is omitted there.
