Revert `variant` handling in V3

HeroUI is a great library, the best I might say. I’ve been a user for years both on the web and even on desktop with apps like Rclone UI, also joined the PRO membership.

In essence, I love your work, and I want this great relationship to continue ❤️

We have to talk about the new variant handling, specifically about danger. One thing I disliked about all other libraries is they made danger/red as a variant instead of a color. HeroUI V2 handled it best by having it as a color.

btw, shadow variant will be missed too, but I get the reasons to remove it. danger however is a different thing and needs to be looked at imo.

The V3 Chip component has danger as a color prop, as it should. These differences hurt both users and llms.

Thanks
