Fix scroll-triggered loading permanently stopping after one round

onScroll() throttled via requestAnimationFrame with a guard
(_scrollRaf) reset from *inside* the rAF callback -- if that callback
ever failed to fire (reproduced via a backgrounded/non-visible tab,
where browsers routinely throttle or suspend rAF), the guard stayed
true forever, silently dropping every future scroll event. Matches
exactly what was reported: the window extends once when scrolling
toward the past, then stops responding to scrolling at all.

detectCurrentYear()/checkEdges() are cheap (DOM reads + early-return
guards, do no real work themselves), so there's nothing worth
throttling here -- removed the rAF entirely and call both directly on
every scroll event. Verified live: repeated scroll-to-top no longer
gets stuck after the first extension, keeps loading older months
across many rounds.
