feat: detect slightly-larger-than-body text as headings

Lines with font size 1.10-1.20x body text that are standalone and short
(1-8 words) are promoted to headings. This catches academic paper
headings where the font is only ~10% larger than body text, below the
previous 1.2x threshold.

Also syncs the simpler to_markdown_from_lines path to match the
table-aware path (removes stale colon exclusion).

Benchmark improvement: MHS 0.54→0.56, overall 0.761→0.766.
