/**
 * Detection Funnel — PRI-446 thin adapter
 *
 * The pure three-layer funnel logic (LRU cache, async queue, layer dispatch)
 * now lives in principles-core
 * (runtime-v2/detection/detection-funnel-policy.ts). This file is a thin shell
 * that wires DetectionFunnelCore with the two environment-coupled dependencies
 * the plugin owns:
 *   - crypto.createHash (the L2 cache key hasher)
 *   - PainDictionary.match (the L1 exact matcher)
 *   - shouldIgnorePainProtocolText (the protocol-token gate)
 *
 * It re-exports DetectionFunnel (same class name + constructor signature) and
 * DetectionResult so DetectionService and llm.ts keep working
 * unchanged.
 *
 * ERR checklist:
 * - ERR-011: this is a thin adapter delegating to core pure logic.
