Integrate AI Agent Services and Chat Interface

- Added support for AI agent services, including `ConversationalAgentService`, to facilitate user interactions through a chat interface.
- Implemented `ChatTUI` for a terminal-based chat experience, allowing users to send messages and receive responses from the AI agent.
- Updated `EditorManager` to include options for displaying the agent chat widget and performance dashboard.
- Enhanced CMake configurations to include new source files for AI services and chat interface components.

This commit significantly expands the functionality of the z3ed system, paving the way for a more interactive and user-friendly experience in ROM hacking.
