/**
 * Lab trend analyzer — deterministic reference-range and slope rules.
 *
 * PURE / NO network / NO LLM / NO Date.now() / NO async / NO fs.
 * Identical input => identical output.
 *
 * ADR-3: The LLM NEVER performs arithmetic. All trend math is delegated exclusively to
 * NumericsQueryLayer.getLabTrend (slope + latestValue). No hand-rolled slope arithmetic.
 *
 * Rules:
 *   A. Reference-range crossing: latestValue outside [referenceLow, referenceHigh]
 *      → kind 'watch' (severity 3, urgency 3);
 *        >20% beyond the edge → kind 'risk' (severity 4, urgency 4).
 *   B. Slope-toward-edge: slope != null, value is in range, trending toward the nearer
 *      reference edge with a projected crossing → kind 'watch' (severity 2, urgency 2).
 *
 * Abstains (empty findings) when sampleCount === 0 for a biomarker.
 * Reference range is read from store.getLabSeries (LabTrend does not carry it).
