LDT-2852 - Cloud Communication - SW - 01 - Realtime data transfer - R&I - 05: DEV - Feature Implementation
- Added MsgProtoUtils_h.jinja and MsgProtoUtils_cpp.jinja templates generating struct <-> protobuf conversion utilities (LeahiMsgProtoUtils.h/.cpp).
- Added write_msg_proto_utils_header/source to MsgCpp.py and a --proto flag path in GenerateMsgDefsCpp.py to produce the new files.
- Removed the proto flag from write_msg_defs_header/source and the MsgDefs templates so MsgDefs no longer embeds protobuf utilities.
- Updated MsgUtils.cmake to declare the MsgProtoUtils outputs and template dependencies, and CMakeLists.txt to list the generated files.
- Removed the obsolete ProtoInterface.h/cpp.
- Updated LeahiRtController to include LeahiMsgProtoUtils.h.
- Added MessageDispatcher to MsgUtils.
- Updated LeahiRt main.cpp signal handling to use signalfd + QSocketNotifier for graceful shutdown inside the event loop.
- Updated tools/CMakeLists.txt to build AgentSim.
- Updated AgentSimController::handleMessage to output received message protobuf to console.
