refactor(review): shell current-thread runtime + единый дефолт; PowerClient parse_enum; тесты на ipc::names

- shell: new_current_thread рантайм (без пула на холодном старте, #11); единый Initial::default().
- PowerClient: generic parse_enum (убрал 3 копии map_err).
- ipc::names::power::MOCK_IFACE; интеграционные тесты — через ipc::names (не хардкод).
