fix(consume): add explicit plugin registration for simulator-specific configs

With the move to hive_tests/, the simulator-specific conftest.py files are no
longer automatically discovered. Add explicit plugin registration to ensure
_supported_fixture_formats and other simulator configs are properly loaded.

- Add command_name parameter to HiveEnvironmentProcessor.
- Register simulator-specific plugins based on command name.
- Update ConsumeCommand to pass command_name to processors.
- Fix AttributeError: 'Config' object has no attribute '_supported_fixture_formats'.
