Margus Veanes 07c797c32b seq_split: dedup identical <D,N> pairs in intersect (sound, memory-only) ... A split-set denotes the UNION of its pairs, so identical (hash-consed) <D,N> pairs are redundant; skipping them in the De Morgan cross-product cuts the materialized split-set ~7x on L15 negcount (65536 -> 9216) with no behaviour change (verified L11 sat / L14 unsat). NOTE: memory-only -- it does not fix the underlying combinatorial blow-up of complement()'s structural De Morgan on a concatenation of predicates (root cause; see spec analysis). Adds nseq-split-dedup-drops counter. Easily reverted if a derivative/minterm-based complement supersedes the cross-product.
