feat: introduce room management and agent selection in TUI

- Added a `CreateRoomScreen` modal for creating new rooms with agent selection and engagement options.
- Updated the main TUI layout to include a sidebar for room management, allowing users to create and switch between rooms.
- Enhanced the configuration handling to support room definitions and engagement modes.
- Refactored existing code to accommodate new room functionalities and improve overall structure.

These changes enhance the user experience by enabling better organization and interaction with multiple agents in the CrewAI framework.
