Enhance AI Agent Integration and Tool Command Functionality

- Added support for JSON in CMake configuration for AI integrations.
- Implemented new tool commands: resource-list and dungeon-list-sprites.
- Created ToolDispatcher for managing tool command execution.
- Refactored CMake structure to include agent sources and improve build configuration.
- Updated agent roadmap and README documentation to reflect current status and next steps.
