Three parser quality bugs observed on prod (Базовый 52 sweep, 132 rows):
A. RE_ITEM_AREA captured year+area concat like '202442,6' from chunked text
where DOM whitespace was stripped between publish-year and area tokens.
Added negative lookbehind + 4-digit cap on whole part.
B. Same regex sometimes matched a sub-fragment '2,2' inside '52,2' — same
root cause, fixed by the tightened regex.
C. publish_date / removed_date were assigned by page-text order, not
chronologically. ~1% of rows on prod had removed < publish. Sort the
parsed date list before splitting.
Cap from prior PR #538 stays as belt-and-suspenders for any junk that
still slips through.
