-- Migration: Normalize Player.franchise to city-agnostic values
-- Date: 2026-01-07
-- Purpose: Enable cross-era player matching for AI rosters by normalizing
--          franchise values to match Team.sname (e.g., 'Oakland Athletics' -> 'Athletics')
--
-- IMPORTANT: Backup database before running!
-- Run on dev first, verify with: SELECT DISTINCT franchise FROM player ORDER BY franchise;
-- Then run on prod.
--
-- Rollback: See inverse statements at bottom of file
