Lean migration: Phase 4 (IterProd + FiniteMap lattices)
- Spa.Lattice.IterProd: k-fold product, recursive Lattice instance,
fixed height k*hA + hB, bot = build of bottoms
- Spa.Lattice.FiniteMap: spine-pinned assoc lists ({l // l.map fst = ks});
with = the 1100-line Map.agda collapses into positional 'combine'.
Same lemma inventory (membership, locate, updating, GeneralizedUpdate,
valuesAt, Provenance-union, le_of_mem_mem) — Nodup is now an explicit
hypothesis where the Agda Map carried it intrinsically. Fixed height
|ks|*hB still via transport along the IterProd isomorphism, which no
longer needs Unique ks (representation is canonical).
