Run Copilot code review on GitHub-hosted runners

[rtBot]

This repository is public, so Copilot code review cannot use rtCamp self-hosted Actions Runner Controller scale sets, which are not exposed to public repositories.

Adds .github/workflows/copilot-code-review.yml, which pins Copilot code review to ubuntu-latest. The file takes precedence over copilot-setup-steps.yml and over the organization-level runner type for Copilot code review only; Copilot cloud agent keeps using the organization configuration.

No dependencies are installed: Copilot clones the repository and provisions what it needs itself. Repository-specific setup steps can be added to this file later if a review needs extra tooling.

Pull request overview

Warning

Copilot couldn't run its full agentic review because it didn't start before the timeout. Make sure your repository has a runner available, or add a copilot-code-review.yml file specifying one with the runs-on attribute. See the docs for more details.

Adds a repository-level Copilot code review workflow to force Copilot reviews to run on GitHub-hosted runners (ubuntu) for this public repository, overriding org-level/self-hosted runner configuration for Copilot code review only.

Changes:

• Add .github/workflows/copilot-code-review.yml defining the copilot-setup-steps job.
• Configure the job to run on ubuntu-latest with minimal permissions and a no-op/placeholder step.
