How GitLab measures Red Team impact: The adoption rate metric

Introduces a new metric for measuring Red Team impact: the adoption rate of recommendations. Details the implementation using GitLab issues, labels for classification (RTRec::Detection, RTRec::Control, RTRec::Process) and lifecycle tracking (RecOutcome::UnderReview, RecOutcome::InProgress, RecOutcome::Backlogged, RecOutcome::Blocked, RecOutcome::Adopted, RecOutcome::PartiallyAdopted, RecOutcome::NotAdopted). Leverages GitLab Query Language (GLQL) to create dynamic dashboards for monitoring recommendation status and trends. Discusses lessons learned regarding early metric implementation and cross-team collaboration.
