/**
 * Test factories — build typed in-memory entities for unit tests.
 *
 * Each factory returns a fully-populated object with valid defaults.
 * Pass an overrides object to customise specific fields.
 *
 * IDs are generated with a deterministic counter so tests produce stable,
 * readable values (e.g. "staff-1", "client-2") without needing crypto.
 *
 * Usage:
 *   import { buildStaff, buildClient, buildPet } from "./db/factories";
 *
 *   const manager = buildStaff({ role: "manager" });
 *   const client  = buildClient({ name: "Alice Smith" });
 *   const pet     = buildPet({ clientId: client.id });
