paginate: mark the boundaries inside avoid boxes once, not per boundary per page - #144

…ry per page allowed scanned every break-inside: avoid group for every candidate boundary on every page; a print stylesheet that sets break-inside: avoid on table rows (Wikipedia's does) turns a long table into thousands of groups, and a page of the countries table took 13.7 s to paginate, the Go article 3.9 s. blockedBoundaries now sweeps the groups once with a binary search each and a difference array, so a boundary's verdict is a lookup. Same breaks (the answer key and every synthetic case pass); 10 000 avoid rows paginate in the test's budget. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Wikipedia's print stylesheet sets it on table rows, so the countries table paginated in 13.7 s and the Go article in 3.9 s (html2pdf's bench, fragmentation stage).blockedBoundariesnow sweeps the groups once (binary search + difference array); a boundary's verdict is a lookup.
