glmark2 (terrain) and vkmark (texture) now each run one ~10s scene instead of
the full multi-scene sweep, cutting the headed part to about a minute. Scene
seconds and the vkmark scene are tunable via GLMARK2_DURATION, VKMARK_DURATION
and VKMARK_BENCH.
Headless + headed suites with power/thermal logging and efficiency reporting.
Includes PassMark, llama.cpp, app workloads (LibreOffice/GEGL/Inkscape/GIMP),
a GOVERNOR selector, compare-report.py, and captured results.
