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
