GitHub Copilot integration for Microsoft Agent Framework

The `agent-framework-github-copilot` library integrates the GitHub Copilot SDK with the Microsoft Agent Framework, providing Python developers with powerful coding-oriented AI capabilities. These capabilities include shell command execution, file operations, URL fetching, and Model Context Protocol (MCP) server integration. It is part of the broader Microsoft Agent Framework, which has unified previously separate AI frameworks like Semantic Kernel and AutoGen. The library is actively developed, with its current version being 1.0.0b260409, and receives regular updates.
