/**
 * Hoist-safe simulator mock factories.
 *
 * Usage in a test file:
 *
 *   import { vi } from 'vitest';
 *   import { simulatorMocks } from './helpers/hoistedMocks';
 *   const m = vi.hoisted(simulatorMocks);
 *   vi.mock('../simulation/AVRSimulator', () => ({ AVRSimulator: m.AVRSimulator }));
 *   vi.mock('../simulation/RP2040Simulator', () => ({ RP2040Simulator: m.RP2040Simulator }));
 *   ...etc
 *
 * Each call to `simulatorMocks()` returns a fresh batch of `vi.fn()`
 * constructors — because `vi.hoisted` runs at hoist time, before any
 * regular imports are evaluated.
