fix(layout): veto side-by-side split that cleaves a rect table (#156)

A 4-column compliance table (labels + Small/Medium/Large) was emitted
as two separate tables: split_side_by_side read the text gap between
the ruled and remaining columns as a page-layout gutter, and each band
then detected its own fragment.

Before accepting a side-by-side split, check rect clusters near the
boundary: if a table-shaped cluster spans it (or ends at it with
cell-like text row-aligned beyond), and those table rows account for
the majority of far-side text, the split runs through a table — veto
it. The majority guard keeps legitimate splits on pages where a figure
spans two prose columns.

target doc +0.506, no regressions.
