Lazy loading dark background causes sporadic performance issues

[orlangure]

Commit b3934f5 for some reason started causing major sporadic performance issues in my environment: the call to HasDarkBackground sometimes takes up to one minute to complete. About 50% of the time everything runs smoothly, and other 50% it gets stuck for at least a couple of seconds.

When checking out to v0.5.0 and running git revert b3934f5, the problem disappears. The issue exists on master as well.

My environment:
Alacritty 0.10.1
Tmux 3.3
Macos 12.4

Thanks for creating the issue. This is a timing issue, where both tea and lipgloss try to query the background color from the terminal. We have a fix for this in the next releases of both tea and lipgloss!
