Fixes: #14839Fixes: #14796
This PR fixes an issue in the Vite extension where we previously only
ran a small list of allow-listed plugins for the second stage transform
in the build step. This caused some CSS features to unexpectedly not
work in production builds (one such example is Vue's `:deep(...)`
selector).
To fix this, I changed the allow listed plugins that we do want to run
to a block list to filter out some plugins we know we don't want to run
(e.g. the Tailwind Vite plugin for example or some built-in Vite plugins
that are not necessary).
## Test plan
This PR adds a new integration test suite to test interop with a custom
Vite transformer that looks like this:
```js
{
name: 'recolor',
transform(code, id) {
if (id.includes('.css')) {
return code.replace(/red/g, 'blue')
}
},
}
```
I also validated that this does indeed fix the Vue `:deep(...)` selector
related issue that we were seeing by copying the repro of #14839 into
our playground:

You can see in the screenshot above that the `:deep()` selector
overwrites the scoped styles as expected in both the dev mode and the
prod build (screenshotted).
Furthermore I reproduced the issue reported in
https://github.com/tailwindlabs/tailwindcss/issues/14796 and was able to
confirm that in a production build, the styling works as expected:

Lastly, I created a repository out of the biggest known-to-me Vite
projects: [Astro, Nuxt, Remix, SolidStart, and
SvelteKit](https://github.com/philipp-spiess/tailwind-playgrounds) and
verified that both dev and prod builds show no issue and the candidate
list is properly appended in each case.
