feat: update base colors

* We now export Spacing and Border Radius as objects again.
* Switched to using asdf rather than nvm so we can use bun to run typescript files.
* Ad-hoc re-coloring of the Skeleton due to color changes and added a story for it to test

BREAKING CHANGE: All `--primary` variables are now removed, if you needed the value for our logo use `--brand-static` in all other cases use `--brand-primary` which is a light/dark aware purple “primary” color.
