Tailwind v4

[irsyadadl]

This PR updates the project to Tailwind v4, introducing major changes across all components. As Trac doesn’t yet support Tailwind v4, utilities such as hover: have been replaced with data-hovered: and similar alternatives.

If you have time, you can test this PR by cloning the repository:

git clone -b tailwind-v4 https://github.com/irsyadadl/justd.git justd-tw4

cd justd-tw4

bun first-time

Grid will continue to have issues unless we address them, or unless the Tailwind variant provides clear guidance on setting up withTv in the tailwind.config which is no longer necessary. You can read more about this in issue 217.
