Behave BDD scenarios (3) tagged @tdd_bug @tdd_bug_592 @tdd_expected_fail
exercise the real ActorRegistry._actor_name() code path with a provider
whose default model contains '/' separators. The tests assert correct
behaviour (exit 0, single-slash names, valid JSON) and fail while the
bug is present; the @tdd_expected_fail handler inverts results so CI
stays green.
Includes Robot Framework integration smoke tests (3), ASV benchmarks (3),
and a shared FakeProviderInfo/FakeProviderRegistry mock in
features/mocks/fake_provider.py.
