GitHub Copilot updates code review API and review overview

GitHub Copilot said on the GitHub Blog that code review settings can now be managed through the REST and GraphQL APIs, from enterprise policy down to individual repositories. The update adds explicit attribution fields, review-effort metadata and source details for skills, MCP servers and custom instructions. It also makes the review overview more compact and includes fixes for billing, automatic retries and reliability. The changes are available to Copilot Pro, Pro+, Max, Business and Enterprise plans.
