Day 4 - Cleanup

Changes

Cleaned up the UI a lot. I like the new heatmap visualization a lot, but it’s a bit slow so I’ll continue to experiment with it.
I optimized the backend a lot, it used to block a full CPU core but now it sleeps properly when idling.
I also expanded compatibility to other Linux environments. This was actually way simpler than I expected, I just happened to start with KDE which is really complex for some reason.

Notes

The dashboard is now live on my website, which you can test with this sample data.
My aim right now is to get the project ship-ready, and then add features one by one.
