Add scrollToLoad and an absent variant of waitFor

scrollToLoad walks a progressively-loading list to the bottom before the steps
that act on its items run. Stopping is two-part: no new matches appeared AND the
container was already pinned to the bottom — counting alone stops early on a slow
fetch. Hitting the scroll cap is reported rather than passed off as done, so a
later step never works quietly on a partial list.

The scrolling element is usually not the window. Lists like this live in a div
with its own overflow, and scrolling the document does nothing at all, so the
step walks up from a matched item to the ancestor that actually scrolls —
overflow allows it and there is more content than fits — with containerSelector
to name one outright when the guess is wrong. Verified against a page whose
document also scrolls, which is the case that tells the two apart: it found the
inner div and pulled 12 items up to 60 in 7 scrolls.

waitFor gains `absent`, for waiting on something to go rather than arrive — a
modal closing after a reset. It only accepts a genuine "selector matched
nothing"; an unreachable extension looks the same from a distance and would
otherwise satisfy the gate for the wrong reason, sending the next iteration into
a page that still has the modal open.

The locate queue carries a free-form options blob now, so a new kind of request
stops meaning a new column each time.

Also fixes a missing comma in the reset flow that broke the build.
