This commit introduces the AgentMessageTile widget, a core component of the chat interface. The widget is designed to display agent messages, including a collapsible section for displaying a pretty-printed JSON code snippet.
The following features have been implemented:
- Rendering of agent title, message text, and expand/collapse button.
- Expandable section for displaying a JSON code snippet, complete with copy functionality.
- A minimum height constraint to ensure consistent appearance.
- Widget tests to validate rendering and interaction behavior.
These enhancements contribute to the overall chat functionality, providing a clear and interactive display of agent messages.
