Automate CI validation for every Copilot suggestion PR:
- Create ephemeral suggestion branches and require branch-protection CI checks.
- Run full unit/integration tests, type checks, linters, and quick mutation tests; block merge on failure.
- Use test-impact selection to run only affected tests and execute in a container matching prod.
- Require human review for logic changes and enable automatic rollback on post-merge failures.
