Fusion a208723cbc feat(FN-2620): add plugin test-time engine resolution stubs
- Add engine-guard-stub test modules for hermes, openclaw, and paperclip runtime plugins to fail fast on unmocked @fusion/engine imports
- Update each plugin Vitest config to alias @fusion/engine to the local guard stub during test runs
- Keep setup-engine-guard behavior while removing dependency on built engine dist artifacts for plugin-local tests

// ── Engine guard ──────────────────────────────────────────────────────
// This setup file installs a vi.mock("@fusion/engine") that throws if
// the real engine is loaded. All plugin tests must mock "../pi-module.js"
// (the seam) to prevent the real @fusion/engine import chain.
//
// If you introduce a test that genuinely needs @fusion/engine:
// 1. Create a setup-test-isolation.ts (HOME override) following the
// pattern in packages/core/src/__tests__/setup-test-isolation.ts
// 2. Add it to setupFiles BEFORE this guard
// 3. Add a vi.mock("@fusion/engine", ...) override in the test file
// or a dedicated setup file to replace the throwing mock

// Resolve @fusion/engine to a local test stub so Vitest can register the
// guard mock without requiring built dist artifacts from packages/engine.
