fred 7ef620cda7 docs: hierarchy schema contract (S2 contract 1, D2) ...

Turns PRD D2/D13 and kanban-SOT Amendment A1 into a concrete schema
contract: companies/estates/platform_projects/workspaces with NOT NULL
RESTRICT parent chains (chain uniqueness by construction), per-parent slug
scoping, hierarchy_grants attachment shape (vocabulary deferred to
contract 2), transfer as single audited parent-FK update requiring
both-sides authority, no owner columns (ownership = grants), fail-closed
bottom-up deletion, Gateway-only mutation path, and a verification matrix
with real-Postgres constraint witnesses.
