[Refactoring] Separation of Agent and ChatAdmin Components

[brunocapelao]

Detailed Description:

• The current code in the MiniAutoGen project includes various components grouped into a single file, encompassing functionalities related to both Agent and ChatAdmin. This configuration, while functional, can lead to maintenance and scalability challenges. The proposal is to separate the components related to Agent and ChatAdmin into distinct files to improve code organization, making it more modular and easier to manage.

Proposed Solutions:

1. Creation of Separate Files: Create two separate files - one for components related to Agent (such as AgentReplyComponent, LLMResponseComponent) and another for components related to ChatAdmin (such as UserResponseComponent, NextAgentSelectorComponent).
2. Code Reorganization: Move the relevant components to their respective files, ensuring that all dependencies and imports are updated appropriately.
3. Documentation Update: Update the documentation and code comments to reflect the new structure and location of the components.
4. Integration Testing: Perform integration testing to ensure that the separation of components does not affect the existing functionality.

Acceptance Criteria:

• Each set of components (Agent and ChatAdmin) must be contained in its own file.
• The code must be functionally equivalent to the previous version, with no loss of functionality.
• All unit and integration tests must pass successfully after the reorganization.
• Documentation must be clear and reflect the new code structure.
