feat: Enhance Networking Documentation and Introduce Automation Bridge

- Updated the networking documentation to clarify the focus on collaboration and remote access.
- Added the AutomationBridge class to facilitate communication between the test harness and the AgentChatWidget, enabling real-time updates on test execution status and plan summaries.
- Implemented automation callbacks in the AgentChatWidget for improved user interaction with harness automation features, including dashboard access and active test management.
