Description

The GitHub Copilot SDK is transitioning to the Microsoft Copilot SDK, and our published skill, plugin, cookbook, and language guidance should reflect the announced name and expanded positioning. This updates user-facing names and transition notes across the SDK content while retaining the currently published package identifiers, imports, and repository URLs because the official announcement says no immediate changes are required.

The cookbook metadata and generated catalogues are updated, and the Learning Hub glossary now distinguishes the SDK from Agent Host. References to old package or repository names remain only where needed for accurate setup and migration context.

🔵 Needs a closer look

The glossary change lacks completed Astro build verification, so a maintainer must rerun it with the repository-supported Node.js runtime before approval.

No open issues 🎉
