- Fix JsonDataNode::getChildReadOnly() to handle JSON array access by numeric index
- Fix test_ui_showcase to use JSON array for children (matching test_single_button pattern)
- Add visual test files: test_single_button, test_ui_showcase, test_sprite_debug
- Clean up debug logging from SpritePass, SceneCollector, UIButton, BgfxDevice
The root cause was that UITree couldn't access array children in JSON layouts.
UIButton hover/click now works correctly in both test files.

Major feature: Unified config/data/runtime tree system
**New System Architecture:**
- Unified data tree for config, persistent data, and runtime state
- Three separate roots: config/ (read-only + hot-reload), data/ (read-write + save), runtime/ (temporary)
- Support for modding, saves, and hot-reload in single system
**Interfaces:**
- IDataValue: Abstract data value interface (type-safe access)
- IDataNode: Tree node with navigation, search, and modification
- IDataTree: Root container with config/data/runtime management
**Concrete Implementations:**
- JsonDataValue: nlohmann::json backed value
- JsonDataNode: Full tree navigation with pattern matching & queries
- JsonDataTree: File-based JSON storage with hot-reload
**Features:**
- Pattern matching search (wildcards support)
- Property-based queries with predicates
- SHA256 hashing for validation/sync
- Hot-reload for config/ directory
- Save operations for data/ persistence
- Read-only enforcement for config/
**API Changes:**
- All namespaces changed from 'warfactory' to 'grove'
- IDataTree: Added getConfigRoot(), getDataRoot(), getRuntimeRoot()
- IDataTree: Added saveData(), saveNode() for persistence
- IDataNode: Added setChild(), removeChild(), clearChildren()
- CMakeLists.txt: Added OpenSSL dependency for hashing
**Usage:**
```cpp
auto tree = DataTreeFactory::create("json", "./gamedata");
auto config = tree->getConfigRoot(); // Read-only game config
auto data = tree->getDataRoot(); // Player saves
auto runtime = tree->getRuntimeRoot(); // Temporary state
// Hot-reload config on file changes
if (tree->reloadIfChanged()) { /* refresh modules */ }
// Save player progress
data->setChild("progress", progressNode);
tree->saveData();
```

Major architectural improvement to decouple interfaces from JSON implementation:
**New Abstractions:**
- Created IDataValue interface for type-safe data access
- All interfaces now use IDataNode instead of nlohmann::json
- Enables future backend flexibility (JSON, MessagePack, etc.)
**Updated Interfaces:**
- ISerializable: serialize() returns IDataNode, deserialize() takes IDataNode
- IModule: process(), getState(), setState(), getHealthStatus() use IDataNode
- IIO: Message struct and publish() use IDataNode
- ITaskScheduler: scheduleTask() and getCompletedTask() use IDataNode
- IModuleSystem: queryModule() uses IDataNode
- IEngine: Removed JSON dependency
- IDataNode: getData(), setData(), queryByProperty() use IDataValue
**Benefits:**
- Clean separation between interface and implementation
- No JSON leakage into public APIs
- Easier testing and mocking
- Potential for multiple backend implementations
- Better encapsulation and abstraction
**Note:** Concrete implementations still use JSON internally -
this is an interface-only refactoring for better architecture.
