test: suppress s3fs/moto async incompatibility warnings in test suite
Add pytest configuration to suppress RuntimeWarnings from s3fs/moto async
incompatibility that occur during test cleanup and coverage instrumentation.
These warnings are expected when mocking S3 operations and don't indicate
real test failures.
Changes:
- Add tests/conftest.py with pytest_configure hook for global suppression
- Add module-level warning filters in test_local.py
- Add @pytest.mark.filterwarnings decorators to 16 mock_s3 tests
- Document warning suppression in mock_s3 fixture
Result: 66 passed, 1 skipped, 0 warnings
