Full rewrite of the gaming deals Matrix bot in Go for better performance and a single static binary. Includes all original functionality (CheapShark, ITAD, Epic free games, multi-currency pricing, dedup, preflight checks, presence heartbeat) plus a new watchlist feature where users can DM the bot to watch for specific game deals with 180-day auto-expiry. New: systemd service file, DB migration script for Python-to-Go transition. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
