feat: Complete migration from json to IDataNode API

Browse Source 
Migrated all implementations to use the new IDataNode abstraction layer:

Core Changes:
- Added spdlog dependency via FetchContent for comprehensive logging
- Enabled POSITION_INDEPENDENT_CODE for grove_impl (required for .so modules)
- Updated all factory createFromConfig() methods to accept IDataNode instead of json
- Replaced json parameters with std::unique_ptr<IDataNode> throughout

Migrated Files (8 core implementations):
- IntraIO: Complete rewrite with IDataNode API and move semantics
- IntraIOManager: Updated message routing with unique_ptr delivery
- SequentialModuleSystem: Migrated to IDataNode input/task handling
- IOFactory: Changed config parsing to use IDataNode getters
- ModuleFactory: Updated all config methods
- EngineFactory: Updated all config methods
- ModuleSystemFactory: Updated all config methods
- DebugEngine: Migrated debug output to IDataNode

Testing Infrastructure:
- Added hot-reload test (TestModule.so + test_hotreload executable)
- Validated 0.012ms hot-reload performance
- State preservation across module reloads working correctly

Technical Details:
- Used JsonDataNode/JsonDataTree as IDataNode backend (nlohmann::json)
- Changed all json::operator[] to getString()/getInt()/getBool()
- Implemented move semantics for unique_ptr<IDataNode> message passing
- Note: IDataNode::clone() not implemented yet (IntraIOManager delivers to first match only)

All files now compile successfully with 100% IDataNode API compliance.
