fix: Suppress test warnings in build_tools Python tests

- Suppress HumanLoopManager deprecation warning in Orchestrator since
  it's intentionally kept for backwards compatibility with batch workflows
- Add pytest.ini to filter RuntimeWarning about unawaited coroutines
  which are artifacts of mocking async code, not actual issues
