The previous ACMSPipeline.__init__ invoked _load_strategies_from_settings
at line 831 before self._strategies (line 834) and self._logger (line 864)
were initialized. When a Settings whose context dict contained a
'strategies' key was passed in, the method body raised AttributeError on
'self._strategies', and the except handler then raised a second
AttributeError on 'self._logger' that propagated out of __init__ and
crashed pipeline construction entirely.
Move the auto-load call to after both attributes are bound. Convert the
pytest-shaped tests/strategies/test_strategy_registry.py (which the
behave-based unit_tests gate never ran) into a behave feature file +
step definitions under features/, matching the project's BDD convention
and bringing the strategy auto-loading paths under actual CI coverage.
