Stage 12w: web runtime performance (D365, D366, D390, D391)
make web-bench measures the exported platformer in Chromium and Firefox
in lockstep, with exact WebGL counters against a per-mode baseline, time
compared with Mann-Whitney and a profile pass that gates allocations in
the engine frame to zero, except listed first-decode and growth sites.

On the web the frame loop fills the audio output, the stream feeder
waits for ring space, per-event allocations are gone and Go allocations
per frame drop from 7.2 to 3.8 in Chromium. The pixel ratio is capped at
1.5 by default (display.maxPixelRatio) and Frame Limit works on the web.
The game loop stays on the main thread; a Worker is not built (D391).
