Pull request overview

This PR updates the Firebolt C++ Actions module so Actions.intent and Actions.onIntent expose the full intent JSON document (serialized as compact JSON text) rather than returning only the "intent" string, aligning client behavior with the updated Firebolt 9 intent shape.

Changes:

• Introduces JsonData::JsonString to serialize arbitrary JSON results/events to compact JSON text (json.dump()).
• Updates ActionsImpl::intent() and subscribeOnIntent() to use the new JSON serializer.
• Updates unit/component tests and the OpenRPC fixture to expect an intent object ({"intent":"...","intentId":N}), while the C++ API continues returning std::string.
