Add scripts/test-value-audit.mjs + scripts/lib/test-value-audit-lib.mjs:
a heuristic that scores every test file under packages/*/src/**/__tests__/**
and packages/dashboard/app/**/__tests__/** from git history, classifying
commits as positive (fix+source co-change, Symptom Verification regressions,
added-with-source) vs negative (flake/quarantine/timeout churn, test-only
modifies, quarantine-ledger membership). Joins per-file durations from
scripts/test-timings.json so SLOW + LOW-VALUE files rank first as deletion
candidates. Emits docs/test-value-audit.json + docs/test-value-audit.md
(top 40 + methodology + caveats). Pure scoring logic is unit-tested with
synthetic commit records. The script never deletes tests — evidence only.
