Replace deprecated identifiers with their new names: - IsLocalAtSource/Target → IsZariskiLocalAtSource/Target - Scheme.comp_base_apply → Scheme.Hom.comp_apply - Scheme.comp_base → Scheme.Hom.comp_base - Scheme.comp_app → Scheme.Hom.comp_app - Scheme.appLE_comp_appLE → Scheme.Hom.appLE_comp_appLE - Scheme.preimage_comp → Scheme.Hom.comp_preimage - Scheme.id_app → Scheme.Hom.id_app - Scheme.comp_coeBase → Scheme.Hom.comp_base - Algebra.Etale.of_isLocalization_Away → of_isLocalizationAway - Module.FaithfullyFlat.of_specComap_surjective → of_comap_surjective - Finsupp.finite_support → Finsupp.hasFiniteSupport - IntermediateField.adjoin_algebraic_toSubalgebra → adjoin_toSubalgebra_of_isAlgebraic - singletons_open_iff_discrete → discreteTopology_iff_isOpen_singleton - IsFinite.finite_preimage_singleton → Scheme.Hom.finite_preimage_singleton - Remove unused simp args: Scheme.id.base, forgetScheme_map_hom, Ideal.coe_comap, Set.mem_preimage, Scheme.Hom.appTop Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
