GitHub Copilot CLI becomes standalone autonomous agent

The transition to a proactive, agentic CLI represents a major shift in how AI-integrated development works in the terminal. It’s no longer just about suggesting syntax; it’s about autonomous execution with local context.

• –Deep integration with local file state and git history allows the agent to perform complex repository-wide tasks without manual user intervention.
• –The move to a standalone binary (replacing the `gh-copilot` extension) simplifies the setup and increases the tool's performance and responsiveness.
• –Multi-model support (Claude 3.5, Gemini 1.5, GPT-4o) and MCP integration provide a flexible, platform-agnostic experience within the GitHub ecosystem.
• –Agentic execution with explicit user approval balances power with safety, preventing accidental destructive terminal actions.
