/**
 * emitSignal - Emits an ISLSignal from an internal ISLResult
 *
 * @remarks
 * Converts ISLResult into a semantic signal (ISLSignal) for AAL/SDK.
 * Aggregates all segment detections (from detectThreats → piDetection);
 * hasThreats and riskScore are derived solely from that aggregation
 * (no separate source of truth). Same ISLResult + same options → same ISLSignal (deterministic).
 * Strategy is fixed at emit time; reflected in ISLSignal.metadata for auditability.
