Will Miao e335a527d4 test: Complete Phase 2 - Integration & Coverage improvements
- Create tests/integration/ directory with conftest.py fixtures
- Add 7 download flow integration tests (test_download_flow.py)
- Add 9 recipe flow integration tests (test_recipe_flow.py)
- Add 12 ModelLifecycleService tests (exclude_model, bulk_delete, error paths)
- Add 5 PersistentRecipeCache concurrent access tests
- Update backend-testing-improvement-plan.md with Phase 2 completion

Total: 28 new tests, all passing (51/51)

"""Integration tests for download flow.
These tests verify the complete download workflow including:
1. Route receives download request
2. DownloadCoordinator schedules it
3. DownloadManager executes actual download
4. Downloader makes HTTP request (to test server)
5. Progress is broadcast via WebSocket
6. File is saved and cache updated
