Copilot Autofix for GitHub Advanced Security for Azure DevOps

Introduced Copilot Autofix for GitHub Advanced Security for Azure DevOps, enabling AI-generated fixes for CodeQL alerts. This feature integrates with Azure DevOps to provide suggested code changes as pull requests directly from the alert surface, aiming to shorten the time from vulnerability detection to remediation. It supports all CodeQL-supported languages and a curated set of high-frequency vulnerability classes. Billing is based on AI credits consumed per fix generation, tracked via Azure Cost Management.
