fix(cli): check root workflow before recommending CI

[skoshx]

Summary

• Check the scan root for the React Doctor workflow in single-project and multi-project scans.
• Do not show the GitHub Actions recommendation when the root workflow is already installed.
• Record tui.ci_recommendation_shown only when the report displays the recommendation.

Product brief

• User job: run a monorepo scan without receiving a setup prompt for CI that is already configured.
• Reuse: use the existing root workflow detector and the existing report surface.
• Compatibility: this removes one incorrect recommendation. It does not change scan results, configuration, or report schemas.
• Success metric: tui.ci_recommendation_shown measures actual recommendation displays.
• Kill metric: remove the metric if it stays unused or cannot measure this surface after two releases.

Validation

• Full test suite
• Lint
• Typecheck
• Format check
• Build
• JSON report smoke test
• React Doctor focused regression: configured and unconfigured monorepo roots

Interactive terminal E2E

Terminal Control verified the built CLI at 5f9b549 in a real PTY:

• selected a project interactively and observed Scanning... before the three-second Git delay completed
• waited for the clean result and exercised the compact report
• opened copy context and the GitHub Actions confirmation, then cancelled safely
