Frohman-S-UnitCorrection: Narrow CohFT Unit 1_J Correction, Seed Family S, and Lefschetz Orthogonality Tables in FJRW Theory

Standalone dataset and technical specification (`docs/CORRECTION.md`, `docs/BROAD_GRADING.md`, `docs/UNIT_INSERTION.md`, `tables/seeds.csv`, `tables/not_seeds.csv`, `tables/broad_grading.csv`, `tables/lefschetz_orthogonality.csv`) establishing the narrow CohFT unit 1_J selection-rule correction for the seed family S in three-block FJRW theory. Records verified selection-rule and grading corrections for the seed list S and narrow unit insertions; explicitly distinguishes closed seed tables from open Hodge/CohFT conjectures.
