Toolkit Workspace — Multi-tenant Team SaaS

A production multi-tenant project workspace: organizations, memberships, invitations, projects, tasks, comments and append-only audit events. Next.js + Fastify + Prisma in a pnpm/Turborepo monorepo, with forced PostgreSQL RLS and a two-role (migration vs application) database model that deliberately rejects superuser connections.
