[eric] browser: OSW_PRESTAGE_WARMUP (default off) = before the aux loop, poll perception up to a wall-clock-bounded 8s so a cold heavy SPA (Gmail/LinkedIn) that just opened is perceivable instead of read-empty-then-give-up; wall-clock (not iteration) bound so a slow/wedged card can't overrun the outer prestage timeout; a page that never settles still fails fast (honest wedge, not hidden)
