feat(gpu): show VRAM in use as a bar with a percentage
Sum drm-resident-vram0 from DRM fdinfo, the same per-client counters
gputop reads, counting each drm-client-id once since a client repeats
its totals on every fd it holds. One grep over /proc/*/fdinfo, about
10ms warm, sampled through new_gate every ~2s.
The 12 GiB total is hardcoded: xe exposes no VRAM capacity in sysfs.
