Overview

Aggregates a flat list of Results into counts, the mutation score, and the surviving-mutant list. The score denominator is killed + survived ONLY (KTD-4): no-coverage, skipped (invalid), errored, and timeout are each excluded and surfaced separately. An empty denominator yields a nil score (rendered "N/A"), never 0.0 — distinguishing "no testable mutants" from "0% killed".
