Remove the Copilot CLI PAT From GitHub Actions Without Losing Your Rollback

Short summary

Copilot CLI no longer requires a personal access token in GitHub Actions. The author provides a migration template: grep for old secret references, remove only the PAT injection without upgrading other components, run a canary workflow proving the legacy token is absent and tasks still pass, then delete the obsolete secret after an observation window. The guide includes rollback procedures and failure classification.
