Configuration Test Script
==========================
Test your Discord bot and RCON configuration before running the main bot.

This script validates:
1. .env file exists and is properly formatted
2. All required environment variables are set
3. RCON connection works
4. Discord bot token is valid
5. Discord channel is accessible

Run this before starting the bot to catch configuration issues early!
