- Adds comprehensive unit tests for AppWorker (22 test cases, all passing) - Adds unit tests for StaticMirroringWorker (30+ test cases) - Adds unit tests for App cluster coordinator (25+ test cases) - Tests cover lifecycle (start, stop, error handling) - Tests cover configuration and environment variables - Tests cover cluster message broadcasting and worker management - Dependency stubs (repositories, adapters, services) Increases test coverage for src/app/worker.ts and src/app/app.ts. Partial coverage for src/app/static-mirroring-worker.ts. Further refinement of StaticMirroringWorker tests needed to properly initialize worker.config before testing isUserAdmitted method. Acceptance criteria for issue #489: - Worker lifecycle tests: ✅ - Error handling: ✅ - Dependencies stubbed: ✅ - npm run cover:unit passes: Partial (need ESM loader configuration)

- app.ts: read WORKER_COUNT from this.process.env instead of global process.env - static-mirroring-worker.ts: read MIRROR_INDEX from this.process.env instead of global process.env - static-mirroring-worker.ts: use optional chaining on this.config in canAcceptEvent and isUserAdmitted since run() may not have been called - static-mirroring-worker.spec.ts: set process.env.SECRET in beforeEach so canAcceptEvent can derive relay public key - app.spec.ts: use fake timers in onClusterExit describe block to prevent 10s restart timer from polluting cli integration tests All 1341 unit tests now pass.

Pull request overview
Adds unit tests targeting previously under-tested app-level orchestration/worker components, and tweaks worker implementations to read environment/config more consistently via injected process and to tolerate missing mirror config fields.
Changes:
- Added new unit test suites for
AppWorker,App, andStaticMirroringWorker. - Updated
StaticMirroringWorkerandAppto prefer injectedthis.process.envfor certain env reads and made some config access null-safe. - Added a changeset entry and a
ts-nodeconfig section intsconfig.json.
