bench: jetson FPS battery — both backends saturate at 80.9 MB scale

Browse source 
Parameterizes the throttle-sweep FPS battery (fpsBattery helper) and adds a
jetson-agx-thor run: asyncify raf 2.1-5.3 / distinct 0.2-0.8 vs JSPI raf
1.9-5.0 / distinct 0.1-0.7 — indistinguishable. Suspension overhead is a
per-event-loop-turn cost; at hundreds of ms of GAL work per frame it stops
discriminating. vme-wren (~27 MB) remains the discriminating size class.
