/**
 * AI layer for Franklin's social subsystem.
 *
 * Two functions mirroring social-bot/bot/ai_engine.py:
 *   - detectProduct()   — keyword-score product router (no LLM, zero cost)
 *   - generateReply()   — calls Franklin's ModelClient for actual reply text
 *
 * Key improvements over social-bot:
 *   - Uses Franklin's multi-model router (tier-based: free / cheap / premium)
 *     instead of hardcoding one model for every call — throwaway replies
 *     can run on free NVIDIA models, high-value leads can escalate to the
 *     top tier.
 *   - x402 payment flow handled by ModelClient — no Anthropic billing relationship.
 *   - SKIP detection lives in the caller so we can commit a 'skipped' record
 *     for visibility in stats.
