Worker shutdown on Windows

littlehorse.start(...) installs shutdown hooks for SIGTERM and SIGINT. On runtimes that do not support asyncio signal handlers (for example, Windows event loops), the SDK falls back to signal.signal(...) when available. If a signal cannot be registered in the current runtime/thread, startup still continues and workers can be stopped by calling worker.stop().
