/**
 * Structured logging helpers for route handlers and cron jobs.
 *
 * Usage:
 *   const log = require('../utils/log');
 *   log.info('economy', 'Daily reward claimed', { userId, amount });
 *   log.error('rooms', 'Failed to close room', { roomId, error: err.message });
 *   log.warn('auth', 'Invalid token', { ip });
 *
 * All calls are fire-and-forget (never throw, never block the response).
