+-- Migration 044: Add provider_detection_data column to dispensaries
+--
+-- This column stores detection metadata for menu provider discovery.
+-- Used by menu-detection.ts and discovery.ts to track:
+--   - Detected provider type
+--   - Resolution attempts
+--   - Error messages
+--   - not_crawlable flag
+--
+-- Run with: psql $CANNAIQ_DB_URL -f migrations/044_add_provider_detection_data.sql
+--
+-- ALL CHANGES ARE ADDITIVE - NO DROPS, NO DELETES, NO TRUNCATES.
