security: replace hardcoded Discord webhook URLs with environment variable

- Remove leaked Discord webhook URL from autologin_no_attack.py
- Replace all hardcoded webhook URLs with os.environ.get('DISCORD_WEBHOOK_URL')
- Add .env.example file with webhook configuration template
- Add .gitignore to prevent .env files from being committed
- Affected files: autologin.py, autologin_no_attack.py, autocraft9x9.py, raidfarm2.py, trader.py, trader2.py, trader_laptop.py, trader_laptopv2.py, trader_wayland.py, trader_win.py, traderv2.py
- Improves security by separating configuration from code
