GitHub Copilot app: The agent-native desktop experience

GitHub Copilot introduces a desktop interface designed for agent workflows. The new experience unifies agent execution, context tracking, and code review in a single environment. It displays real-time agent activity, validation steps, and human oversight points in pull requests. Users can now see what agents tried, what they validated, and where human input is required. This integration reduces context switching and improves traceability in code generation. The feature targets developers using multiple agents simultaneously in their workflows.
