Creates migration 0011 to:
- Create room_game_configs table with proper schema
- Add unique index on (room_id, game_name)
- Migrate existing game_config data from arcade_rooms table
Migration is idempotent and safe to run on any database state:
- Uses IF NOT EXISTS for table and index creation
- Uses INSERT OR IGNORE to avoid duplicate data
- Will work on both fresh databases and existing production
This ensures production will automatically get the new table structure
when the migration runs on deployment.
