Heatmap Bot Update v1.2.0

Just shipped v1.2.0! 🚀

Biggest change: Ko-fi payments now auto-activate.

Previously I had to manually grant paid tier after every payment, not scalable. Now when someone pays on Ko-fi and includes their Discord Server ID in the message, the bot detects it automatically and activates their subscription instantly.

Also added /announce so I can broadcast updates directly to servers that opt in, much better than hoping people check the changelog.
