* fix: don't reclassify wrapped bold list leads as headings
When a numbered/bulleted list item's bold lead phrase wraps onto a
second visual line, that line is all_bold + standalone, which scored
above the rarity heading threshold and was emitted as #### in the
middle of the item. That reset in_list, so the body continuation
below picked up a stray `- ` bullet via the struct-tree LI path,
shattering a single item into heading + stray bullets.
Guard the font heuristic: when already inside a list, skip heading
classification for lines at the list continuation indent with a Y
gap within para_threshold. Structure-tree headings still win.

* fix: tighten rect-row span check in propagate_merged_cells
propagate_merged_cells used an overlap-based predicate with ±tol
slop that returned true at shared row boundaries — a rect whose
top exactly equals row N's bottom lies entirely below the row, yet
the predicate considered it to span row N. When multiple background
rects aligned on a shared Y edge (e.g. consecutive row-stripe
shading), each adjacent rect would over-reach by one row, cascading
labels and data from unrelated rows into a single merged cell.
Replace the overlap predicate with a containment check: rect bottom
at or below row bottom, rect top at or above row top (each within
tol). Genuine merged-cell rects fully contain the rows they span;
tangent rects do not.
Update two snapshots that were encoding the old buggy output.
