/**
 * Read-models module skeleton — RFC-003 Phase 0.
 *
 * Hosts:
 *   - Projector base class (`application/projectors/projector.base.ts`).
 *   - Read-model repository convention (`domain/read-repository.ts`).
 *   - Idempotency port (`domain/projection-offset-store.ts`).
 *   - Per-read-model kill switch (`domain/read-model-kill-switch.ts`).
 *
 * No projectors, repositories, or `IProjectionOffsetStore` provider are
 * registered here yet. The Prisma-backed offset store binding lands with
 * [GOO-187](/GOO/issues/GOO-187); per-read-model projectors land in
 * Phase 2/3.
 *
 * The module is imported by `AppModule` so its DI container is wired up
 * even while empty — keeps Phase 2/3 PRs strictly additive.
