Implement confirm_columns function that partitions page into candidate columns (regions between consecutive gaps + before-first + after-last), counts unique lines whose first span's x0 falls within each candidate's x-range, and promotes candidates with line_count >= 3 to confirmed columns. Supporting code: - ColumnGap struct with lo/hi bounds, width(), midpoint() - detect_column_gaps function for zero-coverage region detection - HasFirstSpan trait for first span bbox access - CandidateColumn struct for tracking x_range and line_count All 49 column tests pass, including all acceptance criteria.
