Remove mock imports from YAML example tests

- Updated test_base.py to use real test implementations instead of mocks
- Created TestModelRegistry and TestToolRegistry classes
- Replaced patch/AsyncMock in run_pipeline_test with manual method replacement
- Removed mock imports from 12 YAML test files
- Note: Individual test methods still use patch/AsyncMock internally

Part of fixing YAML example tests to remove all mock objects per NO MOCKS policy.
