feat: expose D3D capture topology and per-frame draw stats in overlay

Browse Source 
Add guest primitive-type histograms and per-frame DrawStatsSnapshot to frame capture summary so AC6 debugging can correlate point-list draws (trails) and sampler churn with native graphics planning without extra tooling.
