Review Summary: No issues found. All four workflows use only basic tools (Git, PowerShell, GitHub CLI, and GitHub Actions) that are available in the ubuntu-slim image. The migration is appropriate for these lightweight automation workflows and should result in faster job startup times and reduced resource consumption.
