feat: implement Spore framework class as main orchestration layer

- Add Spore class as unified interface for all core framework functionality
- Implement setup() and begin() methods for flexible initialization pattern
- Add service registration with addService() for both raw and smart pointers
- Provide accessor methods for core components (getTaskManager, getContext, etc.)
- Automatically include core services (Node, Network, Cluster, Task)
- Update all examples to use simplified Spore framework approach
- Fix circular dependency issues in include structure
- Remove setHostname and setApiPort configuration methods
- Add comprehensive documentation and usage examples

The Spore class encapsulates all core functionality from the base example
and provides a clean, unified API for the entire framework. Examples now
use just spore.setup() -> add services -> spore.begin() -> spore.loop().
