# Full migration script for player_configs feature
# This script:
#   1. Runs the SQL migration to create player_configs table
#   2. Migrates data from user_preferences to player_configs
#   3. Removes player-related columns from user_preferences
#   4. Regenerates Go models to reflect schema changes
#
# Usage: ./migrate_player_configs.sh
