horizon-ctl gains 'fly' (a constant-speed camera path that replies with the
frame summary); frame summaries add CPU time per frame (waits for the GPU,
display and limiter excluded), per-phase averages and GPU time from timestamp
queries. --offscreen renders into a texture on the discrete GPU so the 4080
can be measured under the headless compositor. Baselines: lavapipe on vscreen
and the RTX 4080 offscreen, seed 1234.
